While waiting for my new-to-me 4S/6T countermarch to arrive, I've been re-reading countermarch tie-up and making plans. In Joanne Hall's new book on warping, she recommends starting with a "standard" tie-up, so that each treadle represents one possible combination of two shafts. e.g, Treadle 1: shafts 1 and 4, treadle 2: shafts 1 and 2, treadle 3: shafts 1 and 3, treadle: 4: shafts 2 and 4, etc.
I like twills, and so had been leaning towards a point twill tie-up (my terminology is lacking here), with tabby on the outside: treadle 1: shafts 1 and 3, treadle 2: shaft 1 , treadle 3; shaft 2, treadle 4: shaft 3, treadle 5: shaft 4, treadle 6: shafts 2 and 4. An alternative would be to put the tabby in the middle: 1, 2, 1-3, 2-4, 3, 4. Ergonomically, that is probably preferable because the knee and ankle would be aligned when lifting two shafts.
I know Claudia is partial to "walking the loom", which I take to mean something like 1-3, 3, 1, 2, 4, 2-4. This ends up being very similar to my planned tie-up, except that the sequence is left foot, right foot, left foot, right foot, rather than left, left, right, right. She generously let me try it out on her loom, but I found adapting to the sequence difficult. I've done 3-1 twills on my navajo loom, and have gotten very accustomed to 1,2,3,4.
So what is the advantage of standard tie-up? What treadling sequences have you found easiest to master?
Thanks,
Mary
