The weaving gods giveth, and…

….human error taketh away.

After about two hours of pulling through knots, I ran into a snag: the knots weren’t pulling through properly.

So I moseyed around to the back of the loom, where, much to my distress, I found this:

Somehow, I had managed to loop the orange warp around the black warp before starting to tie on.

Which meant that I had a major topological problem on my hands. To fix it, I was going to have to cut off, unloop, and retie that entire section of the orange warp, which meant about 2/3 of it. 880 knots, at least.

Since it was going to be difficult, fiddly, and error-prone to retie only the orange-warp knots and not the black-warp knots, it was probably going to be much safer to retie all of the warps on that side. 1,760 knots.

So I did the only reasonable thing, which was to put down the scissors, back slowly and carefully away from the loom, and go have a stiff drink. (Well, a cup of hot chocolate, anyway. I can’t drink alcohol – all it does is make me throw up. Which is a pity, because a couple shots of good whiskey were seriously called for.)

After a couple of days, I came back to the loom, spent a couple hours carefully pulling back and snipping out the knots I had just spent two months tying, un-looped the orange warp, and prepped the warp for re-tying.

Then I looked at the remaining tied-on warp and realized that there was a mis-ordering of the warp in that section as well. It’s a subtle problem, but you can see it in this photo:

As the warps come off the warp beam at the bottom, the black warp is on the inside. But as it passes over the back beam at the top, the black warp is on the outside. It’s twisted.

This might not actually be a problem if I removed the lease sticks holding the threading cross – the threads would straighten out their own ordering and all might be well (I’m not good enough at 3D visualization to tell). However, the lease sticks are my insurance against complete disaster should something turn out to be wrong with the threading. Had I removed the lease sticks before discovering the loop mentioned above, I would be throwing away the warp right now because I would have lost the separate threading cross for the two warps. So no way, no how am I giving up those lease sticks, at least not until I have woven and debugged the warp and made completely sure that everything is working.

However, that means I have to – you guessed it – retie the ENTIRE warp, not just two-thirds of it.

Time to put down the scissors, back away again, and go have an ice cream sundae. With hot fudge and whipped cream, dammit. (Hot chocolate wasn’t going to cut it this time.)

So here I am, two months’ work down the drain, starting over.

Oddly, I am not as discouraged as you might expect. I am also not engaged in self-recrimination. Twenty years of professional experience as a project manager has taught me that disasters happen, and also that there is no utility in pointing fingers when they do. The important part is doing damage control, figuring out how to recover from the disaster and proceed onwards, and (after all that is done) figuring out what happened and how to keep it from recurring. Twenty years of keeping teams from blowing up at each other in the middle of a crisis (and fending off angry executives) does teach one something about staying calm and carrying on.

So: damage control is done, I’ve figured out what needs to be done and am doing it. How it happened? Mostly, it happened because I’m not very good at spatial thinking, and I didn’t check carefully enough that there weren’t any loops or twists BETWEEN the two warp chains when I was setting them up. I’ve never beamed two warp chains onto the same warp beam before, and while I was very careful to make sure there were no twists in each warp chain, it didn’t occur to me that they could be twisted or looped around each other. I left the raddle lease sticks in because they weighted the warps nicely for threading, but they obscured my view of the warp, which meant that I didn’t see the loop in the warp until too late. As far as the left-hand twist went, I just didn’t notice it, or didn’t think it was important, until too late. Next time I know to look for it, and I’ll be much more careful about checking the entire path of the warp from the beam to the heddles while tying on.

I do, however, need something to motivate me while I spend (probably) another two months tying on again. So I’ve gone out and bought a couple new books to continue expanding my interest in folded forms. The one that’s currently exciting me is a book by Paul Jackson, Folding Techniques for Designers. Here’s a pic of the cover:

Folding Techniques for Designers: From Sheet to Form

The whole book is filled with intriguing sculptural forms that can be folded from paper. I imagine I could use stiffened or stitched cloth to create similar sculptural forms. I’m planning to order some heavy bull denim and try starching it to see whether it would be suitable for folding. Or I may weave some 20/2 cotton cloth on the Baby Wolf and try using that for folding, until I can weave something on the jacquard.

I am not sure whether that is compatible with my California fire season theme, but at the moment I’m brainstorming ideas freely, so I’m not wedded to the California fire season theme either. I did see one or two forms that might work well with that theme, though, so I’m not ruling it out either.

So….major setbacks this week, but also some major sources of excitement. Onward and upward!

Revisiting the long-forgotten

After 10+ years’ hiatus, I’ve taken up another old interest of mine: handspinning. A week or two ago, I wandered down to my local yarn shop, Purlescence Yarns, because I had heard they were stocking weaving supplies. In particular, I had heard that they had a computer-driven Louet Megado, which startled me because that is a mighty high-end, complex loom for a yarn shop to be selling. Having a Megado on their floor meant that they were serious about selling to weavers, so I drifted in to suss out their offerings.

I’m pleased to say that we now have a “real” weaving shop in the Bay Area! They have quite a variety of looms, including several types of rigid heddle looms, table looms, and floor looms (both treadled and electronic dobby). Yarns are mostly cotton, I think 5/2, 10/2, and 20/2 cotton. That’s not too surprising since the majority of weavers use those yarns. They have Lunatic Fringe yarns in a rainbow of colors, plus the American Maid yarns, natural color-grown cotton that Lunatic Fringe also supplies. They also have a lot of other weaving yarns, but I have to admit that I was so drawn to the brightly colored Lunatic Fringe yarns that I didn’t much notice the others. (I am a color magpie, in case you hadn’t noticed. 🙂 )

In addition to weaving supplies and equipment, and the expected array of knitting yarns, Purlescence also sells equipment and materials for handspinning. There’s a largish flock of spinning wheels on their shop floor, plus four or five drum carders, and a wall dedicated to spinning supplies – natural, commercially dyed, and hand painted rovings, plus a little bit of fleece. And other spinning goodies, like spindles, hand cards, blending boards, etc.

If you’re in the Bay Area, you should definitely check them out. They’re in Sunnyvale, so South Bay folks (like me!) should be especially excited – we haven’t had a good fiber arts shop down here for ages.

Anyway, I had decided beforehand that I was not buying any more weaving yarn – my stash is embarrassingly large already! But ooh, pretty colors! I wound up walking out with a four-ounce braid of rainbow-colored hand-painted roving, 50-50 silk/merino, from Greenwood Fiberworks. It’s gorgeous.

I was berating myself for the complete uselessness of this purchase (I haven’t spun anything in ten years, don’t own a spinning wheel, and had no intentions of picking up spinning again) when it occurred to me that hey, maybe I could use a drop spindle and spin while walking! I had been trying to get myself to exercise more, but was stymied by my subconscious, which has zero patience for anything it considers unproductive. “Are we done yet? Can we go do something useful now?” Having to listen to your subconscious whining in the back seat for the entirety of a one-hour walk is a real demotivator, so I was having trouble getting myself to go for even short walks.

So I got out my drop spindle from a dusty bin of craft supplies, and tried out the roving. It was a delight to spin, and I quickly discovered that I could spin while walking briskly. And my subconscious did a 180-degree about-face: “Oh, can we do just a few more blocks? I want to make more yarn!”So behold my secret weapon for exercise:

Having started spinning again, of course, it was inevitable that I would acquire a stash. So I bought some roving, and traded with a friend to get some hand cards and some of her fiber stash. I now have about 5-6 pounds of various spinning fibers – enough for several years at the rate I’m spinning.

Since most of my new stash was undyed, I naturally had to put some color in it. So yesterday I hand-painted this roving:

It’s Kraemer Yarns’ Sterling roving – 63% superwash merino, 20% silk, 15% nylon, and 2% glitter. Perfect for a pair of fabulous socks. (And I do mean faaaabulous, dahhhling.)

So after I’m done practicing on the rainbow roving, I’ll start spinning this one. I’m thinking a three-ply yarn, Navajo-plied to keep the color sequence intact, would be perfect.

Meanwhile, I’ve been reading up on another long-forgotten interest, origami. I’ve read the first 200 pages of Robert Lang’s Origami Design Secrets – a fantastic book about designing your own origami models. I haven’t studied it at great depth, but I understand the basic strategies that he’s outlining. It’s very well-written and logical in its progression – you can tell it was written by a scientist! (Lang is a former professor at Caltech, and was affiliated with the Jet Propulsion Laboratory (JPL) for quite some time.) I’m really enjoying it.

I’ve also tried folding some origami tessellations, but have been stymied by my small squares of origami paper. The tessellation I was attempting begins by nonchalantly telling you to fold the paper into 1,024 squares of equal size, so you can imagine that on an 11×11 sheet of origami paper, those squares are very small indeed! (But don’t look so aghast: you can fold those 1,024 squares with just 64 folds.) So I bought some larger sheets of origami-suitable paper yesterday and will try again this week.

I’m also planning to get in touch with some origami masters this week, to see if I can pick their brains about doing origami in fabric. Fortunately several very well-known origamists are in the Bay Area, so hopefully at least one of them will let me buy them lunch. 🙂

But if not, maybe I can pull some strings. After all, I do have friends in high places.

Paper arts

I dove into origami over the last few days, reading up on tessellation origami as well as origami sculpture. I even folded a model or two:

The models are folded out of dampened watercolor paper. Unfortunately, I rapidly discovered a problem with that medium: it is attractive to cats. Very attractive. Here is Fritz, investigating my first model:

I think it was the smell that attracted him: this particular paper, dampened, smells musty, like a wet dog. Unfortunately the paper is also tasty (if you’re a cat) – Fritz rapidly discovered an obsession for licking the paper. I’m pretty sure the glue in the paper isn’t good for him, so the paper went onto a high shelf.

The peacock fan model was only somewhat successful – I had a lot of trouble forming the curved folds. There is an origami enthusiasts’ meeting near me on Saturday; I’ll probably go there to ask for advice on curved folds in heavy paper.

In addition to the books I mentioned in my last blog post, I remembered that I had this wonderful origami book in my library:

"Origami Design Secrets" by Robert Lang — “Origami Design Secrets” by Robert Lang

It’s a hefty tome (583 pages), but promises to be very helpful in understanding origami structures and how to design them.

So I have mostly been reading on origami the last few days.

But yesterday a package arrived with Yet More Inspiration:

"How to Draw" by Scott Robertson and Thomas Bertling — “How to Draw” by Scott Robertson and Thomas Bertling

"How to Render" by Scott Robertson and Thomas Bertling — “How to Render” by Scott Robertson and Thomas Bertling

"Color and Light" by James Gurney — “Color and Light” by James Gurney

"Perspective Made Easy" by Ernest Norling — “Perspective Made Easy” by Ernest Norling

So I expect I have a lot of reading and a little bit of practicing to do, in both drawing and origami, over the next week or so.

This may seem like a scattershot approach – a little bit of this, a little bit of that – but I’ve found that’s how I learn a subject fastest. Particularly in this case, I’m a generalist – I’m not interested in going deep into either form, as my interest in both is entirely ancillary to my interest in weaving. I don’t want to be an expert origamist; I only want to know what I need in order to design intriguing woven origami pieces. Similarly, I am not interested in being an expert artist – just enough to design for the jacquard loom. So I want a broad theoretical overview coupled with just enough practice to understand the basics. Hence the large collection of books, which I will mostly skim to get the underlying principles. If I have time and inclination later, I’ll go back and do a deeper reading.

Of course, there are challenges to learning either art. One of the big ones weighs about twelve pounds, is adorably furry, and finds any open space on my worktable utterly irresistible:

Clearly, under the circumstances, the only possible response is to give him a belly rub. (Or so he thinks, anyway…and he is occasionally right. 🙂 )

A ton of inspiration

Last week was a pretty quiet week, creatively speaking – right up until yesterday, when I innocently went up to San Francisco to see an exhibit, and got dumped into a huge vat of inspiration.

The exhibit was one I’d wanted to see for quite some time – “High Style,” a collection of couture dresses spanning 100 years, from the Brooklyn Museum’s famous costume collection. The accompanying book had been on my Amazon wish list for quite some time – full of luscious dresses. So when I discovered that the exhibit had traveled to San Francisco’s Legion of Honor Museum, I decided to go.

The exhibit is fabulous. If you have a chance to see it, definitely do. It covers a broad range of couture designers over a century of fashion. Fortunately, non-flash photography was allowed in the exhibit, so here are a few of my favorite dresses.

I unfortunately did not remember to photograph the plaque for this dress, so I don’t recall the designer. However, I was very taken with the simple lines and the lovely netted pearls and rhinestones:

And I simply love, love, love the sleeves on this dress by Sorelle and Micol Fontana. At first blush, they look like a cape! I love the drama of the contrasting sleeve and lining, and want to use the idea in a piece. Somehow.

And here, to fuel my phoenix obsession, is a shoe with elegant gold-and-black flames:

Shoe prototype by Steven Arpad — “Shoe prototype” by Steven Arpad

And finally, who could resist? I bought a postcard of this dress to take home and show to Tigress. (She was unimpressed, of course, having her own, far more beautiful, coat.)

But the exhibit wasn’t all. My friend and fellow weaver Alfred (who went to the exhibit with me) and I decided to have lunch in Japantown afterwards. Alas, the restaurant we wanted to go to wasn’t open yet, so we sat down on a bench to show each other our recent work. When we looked up, this intriguing shop was directly across from us:

"Paper Tree" - an origami store — “Paper Tree” – the origami store

If we’d just been walking by, I wouldn’t have noticed it – there are any number of art-paper-and-stationery stores floating around, at least in the Bay Area. But the subtitle, “the origami store,” piqued my interest. About two decades ago I was obsessed with origami, and folded quite a few complex models before giving it up for other pursuits. But I have never entirely lost interest in the art of folding paper. Origami has evolved far beyond the simple paper crane, and a quick look through this shop showed some of the amazing possibilities.

And it may have addressed one of the questions I’ve been wrestling with: what format I want to use for my woven art. I don’t want to do clothing forever, but I enjoy a three-dimensional format; two-dimensional work leaves me, well, flat. But what three-dimensional things could I do with cloth, that aren’t clothing?

Quite a bit, as it turns out. Here are a few of the fabulous possibilities:
