Still More Collapse Cloth -- This Time on 8 Shafts

This summer, for me, will be all about collapse fabrics: I'm teaching a workshop at MAFA and a workshop at the Hartford Artisans Weaving Center, plus I will give a lecture on the topic to the New York Guild of Handweavers.

To prepare, I have been weaving up lots of samples and learning A LOT from the results. (Re-learning a lot, too -- for example, that sett can make the difference between a good fabric and a wonderful fabric. We all know this, but we need to be reminded, particularly if a project should be re-sleyed at a different sett and we get -- well, lazy....)

Anyhow, the samples I've blogged about to date have all been on 4 shafts, because that's the focus of my first workshop at MAFA. In Hartford, we'll be working on both 4 and 8 shafts, so now I've begun sampling on 8. Here are some photos. 

I call these "Before" and "After" shots. The photo above is a "Before" shot of fabric just off the loom. I got the draft from a workshop I took a few years ago in London with Ann Richards, author of Weaving Textiles that Shape Themselves. The warp in this case uses both wool/stainless-steel yarn (the taupe-colored warp, available from Lion Brand and from Habu) and 16/2 bamboo (in red and orange). The weft is 72/2 linen (to give the fabric stiffness) alternating with the wool/stainless yarn.

Here is the "After" photo:

In this case, you have two elements that make this a dimensional fabric: structure and energized yarns. The structure is plain weave with floats alternating weft-wise and warp-wise, so that the floats make room for the fabric to pleat in and out. The wool/stainless draws in and twists when washed, which encourages the pleats to form. Finally, the stability of the linen weft adds crispness to the fabric. Pretty clever, huh? All thanks to Ann, who approaches her art with the mind of a scientist.

Another fabric, this one an 8-shaft double weave, pictured in its "Before" state, showing both front and back views:

The red sections are 18/2 superfine merino from JaggerSpun, which fulls beautifully when hand-washed. The black is 24/2 superlamb from JaggerSpun, which resists fulling because it's a superwash wool. Here's what it looks like, front and back, after hand washing in warm water and agitating with dishwashing soap:

To be honest, the black squares on the front of the fabric don't "pop" the way I had hoped. I was looking for a real dimensional "pouf" in the cloth -- but still I think it works.

Here's another structure from the same warp, before washing, front and back, same yarns.

And after washing:

This sample had a lot more texture, thanks mostly to the floats on the back. It's very thick, suitable for a warm jacket or coat.

If you're interested in any drafts, let me know. It's great add texture to your fabric! And here's one parting shot, of another sample just completed, using the same warp and weft as the first sample in this post but with a different treadling. (This is the sample that you see in the close-up photo that begins this post.)

Happy shape-shifting, y'all!

How Do You Weave This Collapse Scarf? There's a Surprise at the End....

Sometimes when you see something beautiful, you can't get it out of your mind. Which is the case for me with this silk scarf woven by British weaver Sally Weatherill (shown above in detail). I came upon it maybe 3 years ago when I took a workshop with Ann Richards at the Handweavers Studio and Gallery in London.

Here's what I gathered from the photo. Simple fact: It's silk, probably 60/2 silk, in double weave. With two different blocks -- one threading for the blue/green horizontal stripes and one threading for the red/purple. A twill threading, probably a 3/1 tieup.

Too many shafts for my loom, as I have only 12 (a large Macomber and a Leclerc Voyageur table loom). So, for starters, I can't weave a sample in 3/1 twill blocks. Fine with me; I will weave plain weave instead.

Second problem: There is no way I can achieve that small blue/green block in the center of the fabric without adding another block of threading. (That's because the wefts in the red/purple block are discontinuous, right? That weft would have to go in between the middle blue/green block.)

So here's what I came up with.

I used 20/2 cotton on shafts 1 through 4 and 9 through 12 and then 18/2 merino on shafts 5 through 8. I did not like the sample at all (so I won't even post a photo). The weft was 20/2 cotton. The sett was too loose -- so loose that, even after fulling in soap and hot water, the cotton looked like cheesecloth underneath the section where the wool shrank.

Next sample. I decided to tighten up the sett and eliminate the middle block of the warp -- thereby reducing the sample to 8 shafts.

Getting there! Here's how the sample looked.

Still not working well, however. Too messy where the wool warp floats over the merino weft. So I tried weaving the wool block in plain weave right along with the blocks of cotton. Here's the altered draft.

Here are the results. Much better.

I still didn't like the way the cotton plain weave cloth looked after finishing. Maybe it was the matte finish (even though it's pearl cotton). I decided to try superwash wool along with the 18/2 merino, so that the merino would shrink while the superwash wouldn't. I looked at my JaggerSpun color samples and found a red that looked the same in both superwash and merino. The blacks in both yarns matched fine, as you might expect. Here's what the sample looked like before and after finishing.

I like this, but some tweaking is still in order. In any event, I promised a surprise at the end of this post. So, going back to the source of inspiration: the gorgeous silk scarf in blue/green and red/purple double weave stripes.

Remember how I set out to figure out the structure? And it took me three different samples to find something even remotely pleasing -- not to mention the fact that I didn't really figure out the original structure?

Well, through the Complex Weavers Collapse Weave Study Group I have been in touch with Wendy Morris -- a gifted weaver who, at the time I visited the Handweavers Studio and Gallery in London, owned and managed the place. I wrote an article for our study group newsletter discussing the scarf and my efforts to copy it and she wrote me back with this surprise: The scarf was woven SIDEWAYS. Those beautiful red/purple layers are woven horizontally. THAT'S how the weaver achieved the gap in the middle.

Thinking out of the box. I will try always to remember to look at something from a different angle! Thank you, Wendy -- and thanks to Sally Weatherill for designing and weaving the gorgeous piece that got me started on this quest. Here's the draft, for your weaving wonderment.

Deflected Double Weave for Collapse Fabrics

In the immortal words of Yogi Berra, "It ain't over till it's over." This phrase is true not just for baseball, but also for achieving texture in your fabrics. You plan and warp and weave and cut off -- but the fabric isn't finished until it's finished, because it looks entirely different after washing.

Here's an example. Below, the fabric on the loom.

And after washing -- after "fulling" by agitating and scrubbing by hand with soap in hot water, to be exact.

Now THIS is cloth with character! Lots of wriggling shapes, thanks to "differential shrinkage," in which one fiber (wool) shrinks while the other (cotton) doesn't. And lots of strong color, thanks to deflected double weave.

I wove this on my trusty little 4-shaft Structo loom, pictured here.

I have always wanted one and finally purchased one this year. I took it on a trip to Chicago -- and simply packed it in my suitcase. Portable weaving studio!

For those who are interested, the pattern is an adaptation of one designed by Madelyn Van Der Hoogt, featured in the January/February 2007 issue of Handwoven magazine. I altered the threading slightly and substituted 18/2 Superfine Merino by JaggerSpun for the white sections and 20/2 pearl cotton for the black.

Here's the drawdown:

All of this was in preparation for a workshop I recently taught at the Weaving and Fiber Arts Center. The idea was to use an 8-shaft pattern, threaded with 18/2 merino and 20/2 pearl cotton, and create a sampler using lots of different treadlings. The sett is very important for collapse fabrics. For differential shrinkage, you want a loose sett for the yarn that will shrink and a normal (plain weave) sett for the yarn that will not shrink. So I set the merino at 18 epi and the cotton at 36 epi. Same for the picks per inch: I wove the wool at 18 ppi and the cotton at 36 ppi.

This is what the main pattern looked like, before washing.

And here's what it looked like after.

Lots of interest and bold graphic designs. I apologize for the lack of color in these samples -- this blog is named "Random Acts of Color," after all -- but I wanted to create samples that very clearly illustrate what was going on. Deflected double weave is an easy structure to understand, once you get the basics down.

Again,  for those who are interested, here (below) is the draft for the threading and tieup.

The sample above was woven tromp as writ -- but if you're interested in the different treadlings I gave people in the workshop, here they are. (The blue horizontal lines are there simply to visually separate the different treadlings.)

Weave it up, try lots of different treadlings, and remember, it ain't finished until it's finished!
