Note Regarding Dual-Warp Structures

I really enjoyed the process of analyzing the various possible combinations of structures when using 4-end twill and 5-end satin in a dual-warp threading. Putting them down on paper is very satisfying (hey, it's the Virgo in me - I'm compelled to organize things).

For the 4-end twill combinations, I took a draft that I'd woven in the past, changed the warp colors to 2 shades of grey for clarity, and made screen captures of different areas of the draft. In that draft, there were examples of every possible combination. So long as the tie-up contains all three structures (1/3, 3/1, and 2/2) and the interleaved threading spans the entire range of available shafts, you'll see all 9 combinations at least once.

For the 5-end satins, I had to start from scratch, since I've never woven an interleaved threading in satin. But having just analyzed the 4-end twill combinations, it was easy to create the 5-end satin combinations from scratch in Photoshop.

Each family consists of "inclusive" structures, as defined in The Woven Pixel, so when used together there will be no floats longer than the normal floats for the structure (3 threads for 4-end twill, 4 threads for 5-end satin).

The closer I get to actually having a jacquard loom, the more I realize I need to know about structure in order to fully utilize the capability of the loom, and the more time I'm tempted to spend at the computer making Photoshop "pattern presets." But there are tasks waiting in the studio, a warp to get woven off before I sell the Glimakra, and a show in Santa Monica next weekend to get ready for. So for now, I have to restrain myself, and get back to work.

And yes, Alice, I do stop for meals, and mugs of tea, and a glass of wine in the evening :)

The more we know, the more there *is* to know. How exciting!
