Good morning! I have posted the draft and a few beginners notes for this WAL under my drafts. For those who have the Jane Patrick book, its warped up in very similar fashion, and its going to be just as easy to work from her book. For those who are using the extract from the Peter Collingwood book and the magazine article (pdfs attached), this should also be very similar, and perhaps a bit easier to follow. Well I hope so!
Warping up: if you use a cotton warp thread, abut the size of aunt Lydia's crochet cotton, it will make a very nice fringe when you finish as well as being a sturdy warp, and excellent for the string heddles. My warp was a bit fine so I have doubled it, as you can see from the photos, and it is used with a 7.5 inch rigid heddle, and what we call in Australia and the UK a 6 ply knitting and crochet cotton. Its about sports weight. Make sure its mercerised as that is less likely to fray or unspin itself in use. Warp up as a regular plain weave, with the warps through the eyes becoming shed 2.
Sheds 1 and 3 run through the slots. Take every alternate slot warp and place it on one pick-up stick, then put the alternating others on a second pick-up stick. I have used to sets of string heddles, for ease of use, but you can use 1 set and leave the other set on the shed stick, which will stay pushed back to the back beam until needed.
For excellent instructions on how to make continuous string heddles, you can do a search here on Weavo in the Backstrap group, or else see Bolivian Warmi's blog here:
