I liked the green sock yarn I used first with this draft. I wove it to be a wall hanging. The pattern was not squared but elongated.
For this red version I have used 8/2 cotton for warp, 20/2 cotton for tabby and 2/18 wool for the weft. This lighter wool is allowing me to square my blocks. With traditional overshot you are to square your blocks. If I do end up squaring the blocks, I should end up with a square piece of fabric after I have woven once across the threading. Time will tell!!
