Weaving Heartfully: Happy Valentine's Day!



"heartfully." en.oxforddictionaries.com. With the whole heart; with enthusiasm, conviction, or intense feeling; warmly, cordially; devotedly.

What a great word! And what a great draft. I found it online, probably on Pinterest, and I have no idea where it came from, unfortunately. (Update: Thanks to Janice Jones, who kindly sent me an email about this, it comes from Oelsner's Handbook of Weaves, also available as a download from Handweaving.net.) Here's what it looks like in Fiberworks.



16 shafts, a 36-treadle repeat -- perfect for my Toika compu-dobby. I had a 10/2 Tencel warp on hand (wound from hand-dyed yarns by Teresa Ruch, with a solid purple yarn and a variegated red and purple yarn, purchased at Convergence 2018) and I sett it at 28 epi (for twill). The weft is 10/2 pearl cotton in red. Judging from the hand of the fabric on the loom, it's a bit too dense and heavy for a scarf. Perhaps it would work for a purse or a bag for my yoga mat? Then again, the hand might change substantially in the washing....

And then I got to thinking: Valentine's Day is here. So why not take this design and turn it into heart shapes, just by altering the tieup?  

Take a look at the scallop shapes in the tieup above. It's a damask weave, so the tieup is warp-emphasis for the purple sections in the drawdown and weft-emphasis for the turquoise sections. [Damask is defined as a fabric formed from satin (warp yarns floating over 4 or more wefts) and sateen (weft yarns floating over 4 or more warps) weaves, used to create reversible figured designs.] And the motif is split in half, because when you thread a point draw (shafts 1 to 16 and back down to 1), the motif reverses itself, creating the second half of the scallop shape.

I played around quite a bit, working to create a warp-emphasis heart shape against a weft-emphasis background, which required tie-down warps and wefts placed strategically. I had to keep in mind that there would be floats, because you really can't expect to have tie-downs in total symmetry. What's more important is the silhouette of the heart shape.


So here's what the draft looks like now.




I haven't woven it yet, because the original design is still on the loom -- but I could change that easily, right? That's the beauty part of having a computer loom. 

So there you have it, a heartful draft for Valentine's Day! Thanks for reading.

Understanding Turned Taqueté

I think it's Elvis Costello who said, "Writing about music is like dancing about architecture." 

You could say the same about weaving. Writing about weaving is like... painting about cooking. He's making two contradictory points at once, to my thinking: first, that it makes no sense to try to verbalize what is going on -- and second, on the other hand, you may be doing something interesting in the attempt!

Hence, this blog post. 

I'll start with Madelyn van der Hoogt, who defines Taqueté (the unturned structure) as a "weft-faced compound tabby." 

"A weft-faced pattern weave with two or more sets of complementary wefts. Even warp ends separate the weft sets so that one set (color) is on the surface of the cloth and the other(s) on the back. Odd warp ends bind the complementary wefts in alternate (tabby) order, thus the name weft-faced compound tabby, also called taqueté and summer and winter polychrome...."

from A Pocket Dictionary of Weaving Terms for Today's Weavers, by Madelyn van der Hoogt, copyright 1989

In grappling with definitions and drawdowns and actual fabric, I decided to go back to basics, which would be a simple 4-harness threading. It gets clearer and clearer the closer you look. Here's a drawdown for Turned Taqueté, below, threaded on a straight draw with two pattern blocks in the treadling.


Treadles 1 and 2 are the plain weave or tie-down picks, while 3 and 4 are the pattern picks. If you look at the tie-down picks (just by looking at the first treadling block on the upper right-hand corner of the draft), you'll see that the weft is tied down alternately by brown warps on harnesses 2 and 4. That's the tabby in this compound structure. At the same time, warps on harnesses 3 and 1 -- the pattern warps -- are lifted over 3 picks. Back and forth and back and forth, which is pretty much what we weavers do ;o)

So, as Madelyn says, one warp thread floats over 3 picks and the warp thread next to it floats under 3 picks. (This happens alternately, with picks in between, of course, so that the warp floats are not parallel with each other.) But this basic fact is, really, the beauty of Turned Taqueté: you have a pattern on both sides of the cloth, because the structure is warp-emphasis on both sides of the cloth.

Here's another way of looking at it. Since Taqueté (this time, not turned Taqueté, but the original structure, which is weft-emphasis) resembles Summer and Winter, let's compare the two at their simplest level, on 4 shafts.

Above, a simple Summer and Winter pattern using two colors in the weft. You will see that there are weft floats (in blue, floating over 3 warps) and warp floats (in white, floating over 3 picks), with the weft colors defining the pattern. Treadles 1 and 2 weave tabby (so that warp threads on harnesses 1 and 2 are on opposite sheds). Threads on harnesses 3 and 4 are the pattern warps, with two blocks in the treadling to alternate the pattern. If you turn the piece over, you would see the pattern in reverse.

Now let's look at a Taqueté drawdown, using the same threading and the same weft colors. Unlike the Summer and Winter drawdown above, there are only weft floats (floating over 3 warps) and no warp floats of more than 2. But, just like Summer and Winter, if you turn the draft over, you would see a mirror image of what we see here. (That is, where there are white weft floats you will see blue weft floats, and vice versa.) This is a weft-emphasis fabric, while Summer and Winter has both a warp and a weft emphasis.

Now, below, we turn the draft: Threading becomes treadling and vice versa. The tieup changes and the tie-down picks are now on treadles 1 and 2. The structure is the same -- except that we have turned the fabric 90 degrees and weft floats are now warp floats.


This is only a beginning -- and a wordy one at that! Still, it helps me immensely to understand what is going on. My aim is to design more complex patterns that maximize the potential of this structure, because it allows for showing off colors and patterns.

Thanks for reading, and thanks so much to Betz Frederick in Phoenix, Arizona, who has asked all the right questions and contributed so much to my own understanding! Here, for your viewing pleasure, is a photo of a scarf she recently completed, a network-drafted Turned Taqueté pattern using two painted warps in an extended parallel threading.
