Today, I was thrilled to receive my first edition copy of Of Coverlets the Legacies, the Weavers. I am having trouble reading the drafts. On page 33 there is a two block draft that I have been trying to decipher. If I am reading it correctly Block A (the right hand block) should be threaded (1, 2,2,2,2) X 10, 1. What I am really have trouble understanding is the symbols beneath the threading. They read, II S (21U). It is my understanding that that the II indicates a two shaft pattern. The S according to the key indicates Sequence. What does this mean? That it is to be treadled as drawn in? Does the (21U) mean that the block should be treadled 21 times star fashion? Any clarification, would be greatly appreciated. By the way, I highly recommend the book :)

If you can believe AI (and I hold a good deal of scepticism as I have been caught before today):-

21U typically stands for 21 ends/picks Up (raising 21 warp threads or inserting 21 pattern lifts), while II S or 2S refers to a 2-shaft or 2-step secondary sequence in specific pick-up or tapestry notation charts.

21U: Lift 21 threads up

don't know if this helps figure things out for you?
