I have come to the left side of the warp by following the threading blocks. So far this one complete repeat across the warp is at the 28 1/2 inch mark.
I will go back to the right side and 'read' the blocks from right to left again. The beginning block on the right side showed I was to weave three picks. (which makes the correct block be six picks). I will not weave the edge twill threads until I am ready to finish.
