AGWSD Summer School 2015

There is a lot to say about Summer School and I’m short of time, so pictures will have to do their ‘thousand words’ thing. But here’s a quick summary. The Summer School of the Association of Guilds of Weavers, Spinners and Dyers (AGWSD) takes place every two years, in a different location. (If you want to know about the AGWSD, follow the link at the bottom of the post).

This year we convened at Moreton Morrell, at an agricultural college in Warwickshire not far from Stratford-upon-Avon. The arrangements for the 17 courses were immaculately prepared by the organisers, although some tutors and students faced various challenges in their allotted teaching spaces. In mine, for instance, wooden wall panels had been fitted to cover walls, and the holes in them had been cut too small to allow a plug into the sockets behind. As we were working in the joinery department, this caused considerable merriment, and resulted in creative arrangements of extension leads – the admiration of all knitters at Summer School. I should add that the department staff came to cut the panel holes larger and were more than helpful.

The intensely blue floor was an unexpectedly complicated colour distraction when working on sheer scarves stretched flat. It was hard to see the true colours of the dyes. Needing somewhere to hang drying work, I searched in vain in the workroom for suitable points to fix a line. Eventually a group of rebels set up a washing line, trespassing into the stables (no, no horses, just heaps of old chairs).

The course

I taught two identical courses on wax resist which ran back-to-back, and lasted two-and-a-half days each. These short courses, taught by several of the tutors, were designed so that students could follow two sets of studies in the week, and allow the possibility of a shorter stay. I have to admit that as an ageing tutor I found the two-course arrangement tiring. It demanded two inputs of ‘startup’ energy in an already exhausting week: on the plus side it meant that I could teach 20 students, not just 10.

Students used a range of traditional tools such as Indonesian tjantings, Ukrainian kystkas, Japanese ro-fude brushes and a Gambian tool made of a handle wound with copper wire. I also brought a motley crew of household brushes, kitchen forks, tractor washers, odd bits of wire and wood which were used to dip into the wax to make marks on the fabric. Students then dyed the fabric surface and built up the work up layer by layer.

The students rose to all manner of challenges, whether creative, personal, age, or health-related, as I realised from the ‘thank you’ card given to me at the end. Their work was inspired and inspiring, many tackling creative dyeing for the first time and declaring themselves somewhat anxious at the beginning. Teaching a few students who already had some experience was good for the group, allowing beginners to see more developed work and to talk through techniques and ideas. I was delighted to re-meet one student I first taught 17 years ago, and see how her work has developed.

The Summer School organisers faced considerable challenges with the demands made on them by the premises and some of the students, dealing with them with patience and grace. They had set up a full après-teach programme to keep us all out of trouble when darkness fell. Our Monday evening talk was given by Association President Jenny Balfour Paul with characteristic enthusiasm and energy. She outlined her travels with indigo, and how it led to writing her recently-published book Deeper than Indigo. Jenny gave a further day of her time to visit all studios and courses the next day, engaging with students and their work.

There were tours (I went to RSC Stratford); a Silent Auction; barbecues; a hog roast; a fashion show, a Trade Fair; and a Fifties party to celebrate the Association’s 60th year. Students stayed up into the wee hours to make Fifties outfits and fascinators. I’m afraid I was too tired to join in the fun and went to bed unfascinatored.

My thanks to all hard-working Summer School organisers, particularly Chris, plus the support team whose names I do not necessarily know. And thanks to my students, for their trust, good humour, co-operation and enthusiasm. Please look at Katie’s blog, linked below, for a student’s view of my course (and the Rigid Heddle course taught by Dawn Willey) at this year’s Summer School.

Shibori: Caterpillar to Butterfly

DSCF6723

Work laid out during dyeing with individual twists held in position

A recent picture posted on Twitter gained me  more re-tweets, follows and favourites than I’ve ever had. I’d been excited to share a caterpillar-shaped tying-and-dyeing which emerged like a butterfly into unpicked daylight. I was using a new set of folds, twists and ties and had a feeling it was going to be successful. While working the piece (and others like it, as left) my studio dyeing area looked like an operating theatre, with clips and ties keeping twists weighted down, or held out of the way so that nothing bled together. Dyeing took me a long time, adding colours one-by-one with an eye-dropper. I then had to wait until it was completely dry before unpicking, which was like eyeing up an interesting-looking present under the Christmas Tree.

Unpicking was a forensic job where a seam-picker and total concentration was essential so I didn’t make an accidental hole in the fabric. I unpicked before steam-fixing, so I also had to keep the work bone dry.

After the work was unpicked, I had, with regret, to iron out the beautiful bumps and wrinkles. Work must go into the steamer rolled flat. Although steaming will help set wrinkles, it isn’t really an option for me. Strong wrinkles last only as long as the work remains dry and I plan to sell these pieces as wearable and washable scarves.

The silk was a georgette 8 (I tried using a 10, but the increased density left me with less interesting dye ‘migrations’). I use dental floss or tape for tying and the metal clips were from shopfitting suppliers Morplan. I think they are used for displaying pairs of socks…. but I use them for endless studio jobs. Morplan don’t still stock the ones I show at the top, above, but there is s similar design online. They are especially suited to work with dyes as the grips can be wiped clean.

The Journal and a few bossy leaves

I’ve recently been up to London to the first Journal meeting of 2014. Whatever time of the year, this long day trip involves a very early start to drive to the station and travel up to London. We start at 11 am and the whole day, even lunch, forms a meeting to discuss Journal matters and plan forthcoming issues. On the chime of 4 pm the meeting ends and the room empties so swiftly you’d think we were all going to turn into pumpkins.  Members disappear to catch their trains – and occasionally, their planes. There is a great intensity to Journal meeting days, quite a few biscuits are eaten and sometimes it’s a bit frustrating. One has the day-long company of interesting textile-y people with whom one exchanges no more than a sentence or two of nothing-to-do-with-Journal conversation. But that’s the way it is. We are all volunteers giving time for a registered charity / organisation and we keep our expenses to a minimum: most of us are able to complete our round-trip to London within the day. If  you don’t know the Journal, have a look at the website.

Australian Journey: Leaves at Katherine

Australian Journey: Leaves at Katherine

Back at home I have been working on a new piece of wax-resist work which started off with one idea in mind but was intruded on, in a most impolite and insistent way, by the shapes of eucalyptus leaves. The direction of the work (and my hand) changed totally. It’s weird when this happens and is, I assume, a luxury not open to certain types of craft work such as weaving, which require more advance planning.

I’m not sure whether the bossy leaves idea will work, but I have dewaxed the silk and it will go into the steamer this week, along with several shibori scarves of a – thankfully – more compliant nature. Then I will creep up on the leaf-piece and see if it’s any good.

This new work is part of the series I call Australian Journey because the designs are based on colours, shapes and ideas from our trip to Western Australia in 2012. There is a bit more about it here and you can find other posts and images by clicking the Australian Journey link in the tag cloud.

Some bits I like: shibori and wax

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.

BB3: Teaching rewards: wax, dye and shibori

Blog-Bite 3 – and almost up to date

It’s great when a student lets me know if something from my course has helped them in their work or studies. Last week I heard from someone on my West Dean course last March . The ‘Brilliant with Pattern’ course introduces several techniques with an emphasis on scarf making, although the skills are useful for general fabric design as well as learning about dyes, wax and silk. The young student who contacted me had just completed a Foundation Course in Sussex. She has been awarded a distinction. She told me she had made her final major project based on what she learned at West Dean and sent me some images, which I have her permission to publish here. Thanks, PJ, and congratulations on your success.

She wrote, about the silk vest in the images: For my final major project I made from georgette silk , the middle panel is actually a print from a photograph I took, using this direct imagery I printed onto transfer paper, then heat pressed onto cotton with an overlay of white chiffon. Then made into a basic top to focus the attention on the print.

More recently I taught two students (J and R) at home. I normally enjoy this: everything is to hand and I don’t have to load the car, drive 200 miles, unload it, sleep in a strange bed with scary pillows and eat too much breakfast every day. There is but one but – and I know it’s something of a cliché.  When students come to me I have to tidy the studio. By the time cleaning operations are complete I don’t recognise the place. Acres of floor emerge, bin bags are filled with things I didn’t know I didn’t need, I am emotionally drained by the stress and I then can’t find a thing for weeks.

Tidy, for once

J and R had a professional interest in learning silk and steam-fixed dye technique. They were already ‘creatives’ which made technical input the most important part of their visit. To realise the designs and garments they planned through the use of wax, resist and dye, they need to experiment with equipment, materials, various dye techniques and resists and work on various weights of silk. Because they live abroad, heat and humidity will play a part in how they work, how dyes need to be stored etc. There was a lot to pack in, from dye basics to some studio safety, steaming, where to buy to buy silk and wax, even how best to label and market work. We discussed various technical issues, such as painting long lengths and supporting the fabric. We had  to improvise this to some extent using workbenches: I don’t have a set of shinshi sticks and these days do not paint fabric lengths.

We worked in the garage for the longer length as the studio isn’t big enough. The garage too had required a moderate tidy but the Maintenance Department (also Catering Department for two days) had already taken care of it.

I am hoping J and R keep in touch – I’d love to see how the two days with me translates and how they solve some of the technical difficulties we discussed.

And I now have a squeaky-tidy studio and am scared to go in.

Shibori, sheep and the power of six

Last week I tutored a day-course in shibori techniques at Ardington School of Crafts. Ardington is a village on the edge of the Berkshire Downs. The venue is housed in a Victorian school, and its large windows ensure good light at all times. It has been imaginatively and calmly adapted for its current incarnation as a craft school and overlooks a traditional English landscape of farmland and trees. This week, with fine weather and leaves at the multiple-greens stage, everything looked at its best.

Students were introduced to the basic principles of shibori and how patterns will build in the fabric through what is a mathematical logic of repeating folds and layers. We worked principally with the equilateral triangular fold which creates hexagon-based patterns through its geometry of six equilateral triangles. I prepared a set of triangular card units showing how this repeat principle works. The positioning (and shape) of the clamped and identical wooden blocks either side of the folded fabric is represented by the white areas in my patterns. The clamping inhibits the flow of dye through the fabric. The wood blocks can be any shape – there is a pattern created by the green-painted triangular blocks below – and placed in any practical position. Block position will dictate the basics of the pattern. You can see from the image (below right) that the blocks do not necessarily prevent dye from entering the fabric beneath the clamped area. They just affect the character of the final pattern which is based on dye dilutions, deliberate drying of work, overdyeing etc.

Students ironed vertical folds in a scarf length and converted the strip to a stack of triangular folds. They checked the wood blocks and protected them with new clingfilm. This enables a clean start each time the blocks are used: wood absorbs dye readily and will mark  work that follows. I advise beginners to work with three colours only, plus dilutant, to avoid shades of mud. Some students admitted they had been sceptical that their seemingly random application of dye would create something so ordered and I think all were pleased with their results.

Below, you can see me opening up the steamer. This has to be done with considerable care, hence the somewhat stressed expression. You can see the roll of paper and scarves, which has been protected with foil at top and bottom to prevent drips entering the folds and spoiling the work. Note that the top piece of foil was dislodged as I lifted the chamber from the boiler.

Many thanks to the students for allowing me to post these pictures and to Faith at Ardington for taking the photos.

Other news: On Thursday 13th June, Jane Deane and I will be working on our dye research at Leewood for the final open-to-the-public time. We haven’t finished our research, but from Thursday on you can’t come to watch us. To check on details, see here.

With shearing time in Devon arriving, local flocks are looking cooler and in the summer-ish sun my nest of mason bees (Osmia) is hyperactive. The bees don’t make honeycombs (that’s another hexagon-based subject) but are laying eggs in the tubes and sealing them in various shades of Devon clay. We are lucky to have culm meadow locally which is filling with textured grasses in some summer sun. But tomorrow it is going to rain.

Australian Journey: wax and dye on crêpe de Chine

Waxed and dyed surface

Detail of finished piece

We made a road trip from Darwin to Perth in late 2012. Ever since, I have been trying to respond to my observations and feelings about Australian colours and landscape through my work. I didn’t want to represent landscape, although one or two pieces have recognisable elements in them, such as trees. I don’t want to blog about my thoughts when I was planning the work except to say that each has to function as a flat or hung painting, and each piece must be wearable.

This, I began to realise, poses a problem. British light + clients don’t always respond well to the colours of Australia as wearable textiles. Australian colours are often vivid, highly contrasting and very, very bright. It’s to do with the intense heat, the light, the colour of the earth, sky and sea.  British wearers often choose muted and more subtle shades to wear.  These suit our pallid, sun-starved complexions and go very well with incessant rain.

So I have no idea if these vivid scarf-paintings will find a UK market.

I have been working with steam-fixed dyes on silk crêpe de Chine, using wax-resist. I have layered up the wax and dyes until the fabric is as stiff as a board. Each wax layer is made from hundreds of waxed brush strokes which undulate over the surface. The layers have sometimes been 8 deep. Before I de-waxed the last piece I weighed it out of curiosity because it seemed really heavy. I found that it had lost 107 grams of wax after I had steamed and soaked out the last wax residue. The piece shown above (all the images are from the same piece) took me several days and was very time consuming, but I am pleased with the technique of multi-layered marks.

This particular piece is about the colours of Broome, Western Australia, where the desert meets the sea in an astonishing cymbal-crash of bright rusty red and turquoise blue. The landscape sketch shows patches of mangrove: crocodiles are often seen in the area.

Natural dye extracts with wax

There’s a lot going on. A deadline for the Journal for Weavers, Spinners and Dyers meant last-minute articles had to be reviewed and proof-read. This coming weekend I am teaching at West Dean in West Sussex, the course is full,  and there is a lot to do in advance. Immediately after getting back from West Dean I start a series of structured historical dyeing experiments at Leewood with colleague Jane Deane – more about the project on this page. The house smells of hot sheep at the moment as I have been scouring fleece. Next week I deliver new work for the spring exhibition at Redearth Gallery… and so it goes on.

Reading that lot, I am not quite sure how I found time to do a little work with Aquarelle liquid extract natural dyes (see my blog post on them here). But I used spare hours to paint the extracts directly onto mordanted silk, using wax as a resist between the layers of dye. The instructions for Aquarelle give details on heated dye baths for fixation but this is not an option with wax resist, because the heat of the dye bath would melt the wax. My plan has been to place dye-painted and partially dewaxed work in the fabric steamer to replicate the heat and damp of a dye-bath. To start with I just used two of the dyes: the liquid indigo ‘Saxon Blue’ and the Himalayan Rhubarb.

NOTE: My comments on the outcome must be read as they stand: they are emphatically not a comment on the effectiveness of the dyes themselves but on the dyes used in this unconventional way.  There is a lot more work I need to do having seen the results.

My working method was as follows:

  • Silk scarf blanks mordanted in 8% alum 2% cream of tartar
  • Dried scarves stretched on a frame
  • Wax applied – in this case and in each layer simple stripes and lines across the scarf
  • Different dilutions of Himalayan Rhubarb (HR) and Liquid Indigo Saxon Blue (SB)  applied to create variations of blue – green
  • After several layers using a similar technique, wax partially removed by ironing cloth between newspapers
  • Work rolled in paper and steamed for one hour (note: I don’t have a thermometer in the steamer. It is brought to the boil every two minutes and turns off for about two minutes)
  • Work dipped in White Spirit to remove residual wax, and rinsed several times

Observations:

The good news is that the dyes have set in the steaming process. Repeated rinses after the White Spirit dip run entirely clear. I lost some of the SB in the first rinses, but this was almost certainly because I notched up the SB concentration to extremely high levels in some areas and probably overdid it. I always think of dyes and dye-sites like a game of Musical Chairs. When the chairs run out, the dye has nowhere to sit, molecularly speaking. It’s more to do with the fibre than the dye.

This experiment shows that it is possible to build quite dark tones by increasing the concentration of dye in selected areas. There are some deep greens. I had wondered if this would be possible, and it looks as though it is.

However, the HR has lost its lovely golden hue (see the original colour centre top) and has dulled to ochre. If you look at the images you can see some in which the steaming paper has picked up a lots of pink from the HR painted areas. The dyed steaming paper is lovely in itself: the red component of the dye has leached into the paper and didn’t fix to the silk. I have no idea why. It could be the mordanting. It could be the paper. It could be that I steamed too long, or steamed too hot. It could be that it would always happen, whatever the steam-time and heat. I now need to  dye silk with all the Aquarelle colours, using their recommended dye bath, to evaluate their ‘true’ colours.

The centre image shows small blotches on a brownish area. These are created by small spots of dye on a wax surface which I failed to wipe off. These are travelling through to the silk surface as remaining wax melts in the steamer, and they then fix. In this case it is not too big a blemish, but it can look smudgy and ruin a design.

On the centre right image there are ugly blue splashes. These weren’t present when the fabric went into the steamer. I think loose dye may have travelled all the way through the steaming paper and I shall use two layers next time.

More puzzling is the bleeding of the SB into areas that had been waxed onto white. You can see these top right and centre left in the images. This can happen with synthetic dyes if the work has been placed too close to the outside of the paper roll. If you imagine the rolled paper in the steamer (see here for an idea of how it looks) there is more moisture reaching the roll on the outer surface when it is in the steamer. If the steamer isn’t up to heat, work on the outer part of the roll receives a lot of moisture, doesn’t begin to fix and starts to wander around – playing Musical Chairs. The solution is to wrap additional paper around the outside of a steaming roll. I didn’t do it this time. I am not sure whether the bleeding is a result of the steaming process or an issue to do with the dyes themselves. This didn’t seem to happen with dyes on the inner part of the roll, so I tend to blame my lack of foresight.

Conclusion

There is a lot to do but I am enthusiastic about the potential for working with Aquarelle with wax. The colours I achieved aren’t particularly exciting because of the dullness of the HR after steaming, and I need to research this aspect. But they have fixed efficiently via the steamer, it does seem possible to use wax as a resist, and to achieve some strong, dark tones. So I am optimistic; I just need a 36 hour day.

Reflections

I happened to mention to a friend that I only look tidy for an hour once every six weeks. This unusual sixty minutes occurs immediately after my haircut – and today was haircut day. Friend suggested that I astonish my blog readership with an image of me during tidy-hour, but I am a bit shy to do that. Instead you shall have a reflection of the svelte-for-a-moment-me in the cylinder of my fabric steamer. I loaded it up this morning with nine shibori scarves, and the three waxed ones which I completed since New Year. The image is wonderful, for in the reflection process I have lost three tons and almost look thin. Other images show the lead up to the steam with making the shibori scarves, removing wax from the waxed pieces and other bits and pieces.
