Extreme Ironing takes place at the start of making folded and clamped shibori and if I’m not in the mood, it can be tedious and exhausting. The next bit is great as it’s working with dyes, but the best is the Christmas Stocking moment of opening up each dyed scarf. That comes after the ironing, but before the steaming.
With wax it’s the other way round. You do the evil stuff after the creative work with wax and dyes is complete. There’s a lengthy sequence of de-waxing, steaming, cleaning and washing out residual wax, etc before the scarves are ready.

Labels, lists, tissue paper and scarves for despatch this morning
But however they are made, all scarves need a sewn-in label, a personal label / swing tag and a price tag with a stock number. My personal tags were designed for me by Chameleon Studio, a local Devon company. We chose recycled card and vegetable-based inks for the two types of label. I have one for natural-dyed and another for synthetic-dyed work; they look different but the design is related. On the left, you can see the two types of label. The buff label with plummy-coloured ink is the one I use for natural-dyed work. The full-colour image on an individual label is actually a sticker which I attach one by one. It was a brilliant idea of the designer’s to reduce costs on printing because sheets of sticky labels are much cheaper than full-colour printing on card. Once everything is labelled and listed for despatch to a shop or gallery there is always a list to fill out and a package to make up, followed by a trek down the hill to the local post office. Post-dog usually helps with this part of the process.
The latest batch of work has gone down to the Devon Guild of Craftsmen whose Christmas Show ‘Make 2013’ begins at the end of this week. It’s open daily from 10 am – 5.30 pm.
I’m back from a trip to the DHA (Dyes in History and Archaeology) Conference in La Rochelle. La Rochelle hosted the ISEND Conference in 2011 and so I was already familiar with the conference venue – a former fishmarket, now the exhibition and conference centre L’espace Encan.
This is a text-heavy post, so here’s a picture of La Rochelle to keep you going.
La Rochelle
A DHA conference annually attracts a wide variety of delegates from various disciplines. This year there were about 90 of us. Our number included chemists, conservators, artists, historians, researchers working with natural dyes, and students at various academic levels. At a DHA conference you can find yourself sitting next to someone from the British Museum, the Louvre or the Rijksmuseum, or an independent scholar who is simply passionate about parchment. It is a friendly assembly and all are welcome. Even if, as a non-chemist, you sometimes sit boggle-eyed through muscular technical papers full of graphs, analysis and molecular data, there is always something to be learned. I’m told that in early DHA days (this was the 32nd meeting!) there was a heavy bias towards these more scientific analytical papers but that nowadays the balance is more even, with a good mix of historic /scientific presentations. The selection committee who choose proposed papers must have an intensely hard job. Of the 24 or so papers accepted, several intrigued me but as none have yet been published this handful of comments remains general.
Purple Parchments
One paper involved the analysis of purple-dyed parchments. Very little work has been done to analyse the source of the purple colour in such codices and as far as I understand, there is currently no scientific evidence that shellfish dyes were used on the parchments. Non-invasive methods are normally used in their analysis, essential if precious manuscripts are to be studied without damage, and these methods can make it more difficult to identify dyestuffs. (With a parchment it isn’t so easy to remove a physical sample as it can be from a textile, where a loose fibre may be available).
There was a mention of dyeing parchment with orchil, and my ears twitched. Last year I was asked to dye some parchment samples with orchil – and dye they certainly did. But it was apparent that the temperatures and immersion involved in dyeing with orchil stiffened and damaged the parchment quality. I felt that this method wasn’t viable. Cold-dyeing seemed to yield a more sympathetic result but I have no idea to what extent the parchment quality was affected as I was only sent miniscule pieces of parchment to dye.
In the post-presentation question session it emerged that the term ‘dyeing’ means different things to different people. Some delegates considered ‘dyeing’ could be the layered painting on of dye and not dyeing by immersion, as working dyers think of it. Now, I should say that I tried painting orchil on too, but soon lost the will to live. It would be immensely protracted to paint on sufficient orchil to build up a good colour. That’s not to say it would be impossible, I just didn’t have the time or the resources to continue.
It will be interesting to learn more about this research. Maybe at Glasgow and DHA 33 next year? The dates are October 30th – 31st 2014.
Shearings and Clippings
Magnified images had been studied by the presenters which showed lumpy-looking particles in the red lake used in several medieval paintings. These indicated that they were reclaimed dyes from red-dyed wool, made into lakes for painting. The reclaiming of red lake pigment dyestuffs from clippings of dyed wool revealed that it made good economic sense to extract the dyes and to reuse them as painting materials. The dyeing of red, from whichever dye source, was expensive and thus waste material might be reprocessed. Again, I encountered problems with a mutual understanding. Initially I was confused by the words ‘shearings and clippings’ which were used by the presenters. I associate these words primarily with sheep-shearing! In the paper the words referred to waste dyed cloth after cutting woven material – or yarn.
The finding of these ‘reclaimed reds’ isn’t in itself new. A 1996 paper by Jo Kirby and Raymond White goes into great detail (find it here) and also lists a number of paintings in which red lake pigment dyestuffs have been found. Have a look. You may be amazed.
Networking
A couple of years ago, at DHA in Lisbon, I presented a paper about the trade in dye lichens from Angola through Lisbon. I have yet to publish this, for several complicated reasons. But I had an interesting conversation with another delegate which led me to sending a very small quantity of dye lichen and a recipe to the University of Évora. I heard no more, and forgot all about it. At La Rochelle my Portuguese colleague and her team presented a paper in which they had measured and tracked the breakdown of the depsides and depsidones (the dye precursors) in the orchil preparation process until purple chromophores formed. Chromophores are the part of the molecule responsible for colour. The chemistry was patiently explained to me in a coffee break and I now understand rather more about the process that before – although I wouldn’t like to take an exam just yet. DHA is great for this kind of contact and co-operation.
DHA=GFZ: A Gremlin Free Zone
If you read the previous post you will now that I was co-presenting a paper at DHA 32 and I wrote about the snaggly-toothed IT gremlins that lurk for unprepared presenters. I am pleased to report that my eminent co-author, Zvi Koren, had done an admirable job on gremlin-bashing (he’s ace at puns too) and everything loaded and presented totally as expected. So did everyone else’s, and we all benefited from calm, unobtrusive technical expertise delivered by Florent Glatard of ARRDH- CRITT Horticole. Our presentation was really well-received but I will not be writing about it until formal publication.
Thanks to DHA 32 organisers Anne de la Sayette and Dominique Cardon
Anne de la Sayette is the Directrice of ARRDHOR – CRITT Horticole, a ‘centre of research, innovation and technology transfer in horticulture’. Dominique Cardon is well known to most natural dyers as author of Natural Dyes: Sources, Tradition, Technology andScience. She is also Emerita Senior Researcher at CNRS, the French national centre of scientific research. CIHAM UMR 5648 CNRS (an institution, not a mathematical equation..) is one of the most important research centres in France for history, literature and archaeology of the Middle Ages. A new book by Dominique is about to be published but I don’t have the details: as soon as I do I will add them to a post.
Carnac
If you have got this far you deserve a pictorial prize. Using photos from DHA is tricky as I feel I should ask people’s permission before posting their images on a blog, so here is something rather special from the trip home.
Orchil lichen on stone at Carnac
One of the Carnac alignments
Viewpoint over Kerlescan alignments
I had never been to Carnac in Brittany until last week and I had no idea of the scale and breadth of the entire site. But it seemed most serendipitous to discover, on some stones of the alignments, a quantity of orchil lichen. Naturally, I did not touch it. But here are some images to reward stalwart readers. The orchil lichen is in the left hand image only.
I’m halfway between two presentations. The first was for the 6 Guilds of Weavers, Spinners and Dyers at Stratford where I spoke about orchil and how the trade in lichen dyestuff reached global proportions in the late nineteenth century. I thoroughly enjoyed my day at Stratford which included a talk by co-speaker Joan Baxter on the way the East Sutherland landscape influences her tapestries. Her recent collaborative work with dancers Between the Web and the Loom was interesting and she showed some video clips. But I can’t find any images on the internet to provide a link beyond this one (about the dance) and this one (about the tapestry she wove).
The second presentation is for the Dyes in History and Archaeology Conference (DHA) in La Rochelle, France. That’s later this week, is about something else entirely, and it’s going to be rather sensational.

Lectures and technology
Those who are of ‘a certain age’ will remember that one of the worst things that could happen when giving a lecture was that you dropped all the slides just prior to going on stage then reloaded them upside down, in the wrong order and back to front.
Technology wasn’t satisfied with such piffling levels of stress. So it created Macs and PCs and system updates; memory sticks and SD cards and PowerPoint and embedding. It now arranges that hosts provide an ancient laptop unable to read anything post 1910; it organises missing leads, the wrong leads, deflating batteries, clickers that die, videos that won’t load and projectors which will have nothing to do with your laptop.
I have watched entirely respectable speakers show a presentation devoid of images because they haven’t checked their Mac presentation on a PC – or haven’t embedded their photos.
As a result I am obsessive about options. At the 6 Guilds event I took my own Mac laptop, own projector, requisite leads plus a boggling array of memory sticks and SD cards correctly formatted and checked out on a neighbour’s PC. In fact, the options proved unnecessary as the 6 Guilds laptop was up-to-date, the memory stick loaded, and two super-calm techies were in control.
For DHA, all presentations have to be sent in advance of the Conference which is good sense – in theory. You will be informed that something has arrived, but you still don’t know if the presentation shows exactly the way you designed it. So, when you get there, you need to check – and have some options up your sleeve. I didn’t do the DHA PowerPoint: my co-author did, for which I am deeply grateful. It can all be his fault.
Lichens in a Canterbury graveyard: from my 1960s sketchbook
In my last post I started to write about orchil, and how I became fascinated by its story through my researches on an eighteenth / nineteenth century Wood & Bedford / Yorkshire Chemicals archive.
To start at the beginning, orchil (pronounced or-kil) comes from lichens. It has been used for millennia to dye wool and silk a purple colour. There is some confusion over ancient recipes for purple. It isn’t always possible to decipher which recipes refer to lichen and which to shellfish dyes. Both dyestuffs produce a remarkably similar colour, were to be found in the same areas (e.g. the Mediterranean coast) and descriptions of lichen are often a little vague. For instance, dyestuff might be referred to as a plant, or a moss, or a seaweed.
There is evidence (Pliny, Theophrastus, Dioscorides) that orchil was used in conjunction with shellfish purple and it’s a ready assumption that this was done to defraud – which of course it may have been. The processing of orchil would have been significantly cheaper than for shellfish dye. But the combination was also undertaken to produce a legitimately cheaper alternative to pure shellfish-dyed cloth. Nevertheless, orchil and shellfish-dyed cloth seems regarded with disdain because of the great and unique reputation of shellfish purple, and orchil’s tendency to fade.
The beauty of fresh orchil on woollen yarn
Orchil dye is extremely beautiful in its first, fresh bloom of colour but it normally proceeds to fade fast. It is therefore interesting to read a 2012 paper (link below) in which Casselman and Terada demonstrated that a combination of orchil and shellfish dye may in certain circumstances, stabilise the orchil. They also reported that the use of orchil as a base dye would to some extent neutralise the intensely unpleasant odour of shellfish-dyed cloth. Those facts cast an entirely different light on the historic combination of orchil and shellfish dye.
It occurs to me that in more recent days, far from being ‘poor man’s purple’, orchil could have been considered a great luxury. If you could afford the rich glories of orchil-dyed silk, and these would be obvious to all by the colour, it might indicate one’s financial indifference to fading and the realities of a soon-spoiled garment.
Dye lichens
Not all lichens will dye, not all dye lichens will make orchil. Orchil-producing lichens (and there are innumerable species) contain precursors of the dye and to make this available the dyestuff must be crushed in ammonia or stale urine and water and then kept well-oxygenated. It undergoes a type of fermentation, and the purple colour develops over several weeks.
Orchil is very sensitive to changes in pH and by adjusting vat strength and acidity, a wide variety of colours can be achieved, ranging from browny reds to reds, pinks and purples.
Crotal / crottles
There are lichens that will dye rusty reds, browns and golds. They are often referred to as ‘crotal’, (a Gaelic word) or crottle, lichen. These require no fermentation and are normally boiled up together with fibre, yarn or cloth. They have been in traditional use in Scotland for centuries and the warm, earthy smell of crotal-dyed yarn is also a moth deterrent. But crotals are not orchils!
Mordants
Neither orchil nor crotal requires a mordant although some historical recipes recommend an alum mordant for orchil.

The Wood & Bedford Orchil Story
I found a vast number of items in the archive which related to the nineteenth and twentieth century trade in orchil. A couple of them can be seen in the previous post. The records defined several sources of orchil lichen. Around 1830 these included Scandinavia, Sardinia, the Azores, Madeira, the Canary Islands and Cape Verde. Political changes and colonial interests affected trading in the later 1800s, as did the slave trade and, eventually, its abolition. A picture emerged of a voracious trade that reached an industrial and even global scale by the mid nineteenth century. There is a certain irony in the fact that stocks of what, in effect, is a non-renewable product were saved by the synthesis of mauveine by Perkin in 1856. The demand for lichen then dropped. Nevertheless, Wood & Bedford, later the Yorkshire Dyeware and Chemical Company, continued to buy and process orchil lichen well into the twentieth century. I understand that the last unused lichen stocks went to Johnsons of Hendon who presumably used lichen to make their indicator papers.
Lichen ethics
You will see that I have learned to make orchil and to dye samples for research purposes but I don’t use it in my studio work. You can read some of my thoughts on lichen use here. I am extremely grateful to all those who taught me about making orchil and how to dye with it.
Pronunciation
How do you pronounce lichens? I say it to rhyme with kitchens. Most people and academics (ok, sorry, academics are also people) say ‘likens’. The OED pronunciation makes it official: you can say it either way:
/ˈlʌɪk(ə)n, ˈlɪtʃ(ə)n/
About five years ago life veered off in a new and unexpected direction.
My neighbours asked me to look at a dye-related company archive they were liberating from their attic. They were selling their house, thought they had a ‘firm offer’ and there wasn’t a lot of time. There would be no space for the archive in their new home and I offered to rescue anything important from its potential new resting place – an unconverted stone barn. I imagined I’d see a small, disparate heap of documents and books descend the attic stairs with little supporting contextual information; honestly, I did wonder how interesting that might be. Because I knew a little about dyes I hoped to advise my neighbours if anyone would be interested in any of the collection before it made its acquaintance with the barn.
Six weeks later (the ‘firm offer’ wasn’t) I had opened and listed the contents of dozens of boxes and trunks containing documents, books, ledgers, patents, dye samples, photographs, letters, diaries, Minutes, catalogues, invoices, plans, maps, contracts, botanical samples, watercolours, chemicals, medals and awards…. and even a mousetrap, devoid of mouse.
Are you beginning to get the idea? Neither disparate, nor without context.
This is some of what I initially learned. The archive had been handed down through my neighbour’s family. He is a direct descendant (the great-great grandson) of a chemist called James Bedford who was born in 1795 and apprenticed to a chemist and druggist in Briggate, Leeds, in 1810. James Bedford was the first in a descending series of three James’, all of whom worked in the family business, which started its life as Wood & Bedford. The same company, though it amalgamated with others and changed names, never underwent a takeover and occupied the same premises in Leeds, on Kirkstall Road, until it went into administration in 2004. It was by then the internationally-known Yorkshire Chemicals.

The Wood & Bedford / Yorkshire Chemicals archive was largely assembled in the early twentieth century by the third of the James’, although it included material from the early 1800s. There was little after 1945 as later material was largely retained by the company and not kept within the family. I published an article in the Journal for Weavers, Spinners and Dyers in 2008 (it can still be downloaded here) which gives a summary of the early days of my research. I was amazed to discover that, contrary to what I had read and often heard, the use of natural dyes persisted long after 1856 when mauveine was discovered by the young William Henry Perkin. Logwood, orchil lichen and various tannins featured in the archive well into the twentieth century, although the company also worked successfully on the development of synthetic dyes.
It’s hard to pin down why I became particularly intrigued by the orchil trade, but an early 1800s dyers’ notebook (there’s a page shown above) certainly helped. My orchil-dyed path, proceeding from the heap of rusty trunks, has since led me to Galicia in Spain, to Posnan in Poland, to Leeds, Lisbon and to Ecuador. In October it’s taking me to La Rochelle, and last week it took me back to Yorkshire. I will be giving a talk on the orchil trade to the ‘6 Guilds’ group of Weavers, Spinners and Dyers at the end of this month in Stratford; at DHA (Dyes in History and Archaeology) in La Rochelle in October I am delivering a joint research paper with Professor Zvi Koren on samples labelled ‘Tyrian Purple’. I can’t say any more about those until after the event – or I would have to leap through the screen and kill you. It’s Classified.
Yorkshire Grit
The Wood & Bedford / YC archive has been accepted by the West Yorkshire Archive Service (WYAS) through the generosity of my one-time neighbours; a ‘firm offer’ did eventually materialise. So the collection has gone back to Leeds where it belongs. WYAS were excited by the fact that the archive covered long periods of the same company’s history. It isn’t yet available for study as archiving is being undertaken by a dye chemist; through a coincidental set of circumstances I was put in touch with a large group of ex-employees of Yorkshire Chemicals (YC), of which he is one. This contact led to my giving ex YC employees several presentations as they knew nothing about Wood & Bedford’s beginnings. Most professed great affection for their time at YC, and one referred to it as ‘the best days of my working life’.
A (sadly) dwindling band of ageing YC folk meet up from time to time and I sometimes join them for the annual outdoor charity Band Concert given by the Elland Silver Youth Band. That’s why I have just been back to Yorkshire. The rest of the country sweltered in tropical heat, but Halifax wasn’t having that. It was practising Yorkshire Winter. The wind Heathcliffed down from the moors with such enthusiasm that tents and gazebos couldn’t be put up to protect the young Band members – who played valiantly in shirtsleeves. A knocky-kneed and freezing set of ex YC attendees cowered under woolly blankets and discussed cryogenic concerts. There’s nout like Yorkshire Grit.
I’ll be writing more about the archive in future blogs, once I thaw out.
Farfield Mill
Some years ago when Farfield Mill reopened as an arts centre, I used to sell work there but I have never visited until this week. The impressive Mill centre is set on four floors which include exhibition spaces, a retail area, the best second-hand textiles bookshop ever, a historical display about wool, weaving and knitting and small workshop / display units. A large industrial working loom weaves blankets and throws next to the Weavers Café – a refuelling stop after the rigours of viewing everything at Farfield. I enjoyed seeing but particularly, handling, Laura Rosenzweig’s Howgill Range which I have only read about in the Journal (issue 243). As Laura’s Loom, Laura runs one of the work and display units. With my next Yorkshire concert in mind, I bought a Shetland wool hat from Angela Bradley‘s shop.
On the top floor we found a welcoming group of weavers, some of whom I know through the Online Guild. They had a variety of looms and equipment on show and in use, and were clearly a valuable asset offering explanations to visitors, many of whom, it seems, don’t know the difference between weaving and knitting.

Several years ago I was fortunate to buy a small out-of-print hardback book in the collection of an Oxfordshire dyer. It was Ethel Mairet’s Vegetable Dyes. Originally published in 1916, the book is something of a classic and my 1952 edition represents its eleventh reprinting. I normally don’t like finding handwritten marks and notes in books but this one has been well-used, and I enjoy thinking of (at least) two dyers before me making use of it.
Ethel Mairet, née Partridge, was born in 1872 in Barnstaple, North Devon, which isn’t far from where I live. Her life was extraordinary on many levels as an influential figure in arts, crafts and education. She was married for a time to a Ceylonese called Ananda Coomaraswamy and travelled to Ceylon with him, studying and documenting weaving, spinning and dyeing techniques. She divorced in 1912 and married Philippe Mairet in 1913. At ‘Gospels’, her house at Ditchling, she set up a workshop and taught students who themselves became influential in the textile world. These include Marianne Straub and Elizabeth Peacock. Elizabeth Peacock has an association with Dartington, also here in Devon, for whom she wove a set of banners in 1938. There is an image of one of them here.
In 1931 Elizabeth Peacock co-founded the Association of Guilds of Weavers, Spinners and Dyers (AGWSD). With others, she organised the first AGWSD Summer Schools and if you have been reading previous blogs about madder and Turkey Red, you’ll know that Summer Schools are still held biennially by the Association. Ethel Mairet taught on these first Schools, so I’m glad her madder recipe emerged with such success at Carmarthen. Opinions change over the years, however, and nowadays dyers tend to use much less alum mordant than the 25% her 1916 recipe recommends. It’s certainly a large percentage for me.

Blessed with some summer sun, I have been drying out the wet madder chips I brought back from Wales. I was surprised at how much the heap shrank as the chips contracted. With the liquid madder exhaust I have used a More-or-Less-Ethel (call it MOLE?) method to dye scarves. It’s ‘more-or-less’ because the exhaust is an amalgam of numerous dyebaths from Summer School and isn’t consistent with Mairet’s recipe. I have also dyed silk with it, and her recipe specifies it’s for wool. But I worked the Mairet long mordant (resting it damp for several days) and the 25% alum and also brought the dyebath to the boil for the recommended ten minutes. Boiling madder is very controversial as many recipes (such as Jill Goodwin’s) advise that raising the heat of the dye bath above a certain point will make the madder go nasty and brown. This is clearly not necessarily the case because our experiments included recipes where we boiled, and those where we didn’t, and Deliberately Boiled Brown became something of a Holy Grail.
If you read my blog regularly you will also know I am a voluntary editor on the Journal for Weavers, Spinners and Dyers which is the magazine of the AGWSD. A new issue (247) will shortly be plopping onto doormats for the attention of international sets of dog-teeth; we are also approaching the copydate for a future issue. So it has been a frantically busy week. All the reports from the recent Summer School are included in 247, as well as regular articles and features.
The Journal is also announcing the appointment of the new AGWSD President, Dr Jenny Balfour-Paul, but this will be in Journal 248. Jenny is best known for her research work into indigo but is passionate about education and the passing on of our skills. I owe my own passion for natural dyes to her: I attended a series of lectures on Japanese crafts at the Crafts Council in the early 1990s (Marianne Straub was another attendee!) and was infected by Jenny’s enthusiasm for natural dyes. She taught me to dye with indigo, and the rest is history.

I’m back home after Summer School. As one of few students on my course who took a car to Carmarthen, I brought back gallons of exhaust madder in containers, as well as a heap of bulgy muslin bags containing chopped and ground root we had used on various projects. I’m glad I wasn’t apprehended by South Wales Police trailing my gory drips: the gooey, oozing bags would have looked at home at an Aztec sacrifice. Maybe police were too busy chasing the rotter who stole tutor Jason Collingwood’s laptop and irreplaceable woven samples, some his late father’s, from his train home from Summer School. The samples have, thankfully, been recovered: they had been chucked over a garden hedge in Neath. Through the kindness of strangers, they will be returned to Jason. The computer is still missing.
Deb Bamford suggested that if I were to empty the bags of chopped madder and dry out the dyestuff I could regrind and re-use it. It will have lost some of its colour in previous dye sessions, but I like the yellow / orange / peach tones that exhaust madder produces on silk and wool. As to the liquid exhausts, I shall be blending them and using them on silk and wool for scarves. I need to get on with this as the liquid is beginning to ferment and there is a noticeable implosion when I open the containers.

The blue gorilla: one of a series currently stalking Exeter
I looked at the vast array of madder-dyed samples we had done on the course and arranged them to photograph, then wondered how many people-hours they represented. I calculated it would have taken one person 66 days to complete the equivalent work over an eight hour day. That’s without the labour put into the Turkey Red preparation by Deb, our tutor.
Why the gorilla? I’ve been going on about red rather a lot, he is a blue gorilla and he is loose in Exeter.

Not the final day of the course, but the final day of dyeing. We have been through all the processes used in dyeing Turkey Red through a long sequence of carefully managed samples prepared by tutor Deb Bamford. Today we dyed the final stage. The temperature of the dyepot was raised and maintained and the prepared fabric was immersed, with one of the group stirring it continuously.
Turkey Red
At the end of the dye period, we lifted the cotton from the pot. We had achieved a good, characteristic, Turkey Red.
Various experiments and variations continued in the room and explanations and notes added to ‘the wall’.
Tomorrow is the last day and for tutors and students, it finishes at noon. For our course, the morning will be spent sorting and sharing samples and clarifying processes.
Deb Bamford is highly organised; if she hadn’t been, this intensely complex course could have descended to chaos and dyeing mightn’t have been completed accurately, safely, or at all. Deb explained everything clearly and directly; she really knows her stuff. The student group has been pleasant, co-operative and multi-skilled, which has added to an enjoyable (and valuable) week.
The Trade Fair opened at the Summer School this afternoon with stands selling spinning and weaving equipment, yarns, books, fabrics and trimmings. I helped set up the stand for the Journal for Weavers, Spinners and Dyers for which I work as a volunteer editor.
Tomorrow classrooms and the Trade Fair are open to the public. In the evening there is a Gala Dinner with a speaker, and then it will be time to pack up and go home.

Two unrelated observations: it has been a great luxury to be on a course as a student and not a tutor, but it’s peculiar that I am more tired this way round.
The other is that they have some mighty fierce mosquitoes in Wales. I had hoped there was an interesting word for mosquito in Welsh, but it seems it’s mosgito. Oh.
I have been writing Summer School blogs late at night and I am forgetting to include things. Here’s what I forgot yesterday: images of the textiles from the Welsh Quilt Centre at Lampeter. They should have been attached to yesterday’s post.

Today, Turkey Red preparations continued and we started to plan the ordering, labelling and displaying of the various samples dyed on the course. We are working in the art college (Coleg Sir Gar) in a Life Room; it’s part of a larger suite divided by folding screens. The screens are also whiteboards and we can write on them with markers, which makes displaying and explaining samples a bit easier. An exchange visit with students on Helen Melvin’s eco-dyeing course took place this afternoon and they could see the first samples together with their recipes and comments from the groups that had dyed them.

‘If you would dye wool into a perfect red colour..’ begins Gervaise Markham’s 1615 recipe from his book The English Huswife.I am in a group-within-a-group on the course; we excel at producing dispiriting pinks from recipes which boast all manner of ‘perfect reds’ as their outcome. I think we have even astonished tutor Debbie by our unerring skill in this regard.
From the selection above, guess which yarn is ours after trying Markham’s recipe. No prizes.
In the dye room this morning we reground the fourth and final exhaust dyestuff for the Turkey Red samples and heated it to temperature so that it could cool before dyeing tomorrow. Debbie has hung the Turkey Red-prepared cloth in the college smoking shelter – which might well discourage smokers from entering and be very good for overall Welsh health.

Many madder recipes state that one should not raise the temperature of the dyepot above a certain point or the colours will turn brown. On the other hand, many recipes have silk or wool boiling for as much as an hour. So what’s going on?
Jill Goodwin advises a maximum of 158 F (70 C). We were careful to follow her recipe yesterday, but today someone suggested we should boil one of the Goodwin skeins to see if it would affect the colour.
So we did, and it didn’t…. and it set us thinking where such advice originates and under what, if any, circumstances it might be true.
Our visit to the museum was interesting but short and there were far too many of us for a comfortable visit. Nevertheless, I enjoyed watching the spinning mule in action, and touring the finishing and weaving sheds. Across in the field was a tenterframe for stretching and finishing cloth, and a windhouse for drying more delicate fabric. The tenterframe looked squeaky-new and unhistoric (do Ikea offer a selection?) but gave some idea of how the field might once have looked.
I came across a set of natural-dyed yarns produced by David and Margaret Redpath who, until 2002, ran Wallis Mill in Pembrokeshire. It was the last commercial mill in Wales to dye with plant materials. The dye garden behind the wool museum was sadly neglected and overgrown with weeds, although some madder was struggling plantfully on.

The Quilt Centre at Lampeter is in the old Town Hall. Currently, and until November, a collection of antique Welsh quilts is on display with work by Kaffe Fassett and other contemporary quiltmakers. There was a time when this modern work would have held all my attention, but now I am old and grey it was the monochrome historic textiles I found the most beautiful. The collection has been put together by Jen Jones, who realised several years ago that these lovely bedcovers were being discarded as having no value. In a short address to the group, Jen said that she had once seen a farmer using an old quilt to keep a sick cow warm. The Quilt Centre exhibition was superbly done, with work suspended at different angles and heights from an immensely high ceiling. Complexities of lighting were skilfully handled so that nothing appeared overshadowed.
This collection is by Moda Fabrics and is called Indigo Crossing
In Calico Kate, a shop for quilting enthusiasts almost next door, I found a set of printed cottons in the blue and white derived from the traditional patterns of resist-dyed indigo. These fabrics seem to be following me around: see this post from earlier this year.
