An article from Master Weaver on designing multi-block double weave patterns. It explains the frame and treadle limits (three blocks on 12 frames and 16 treadles), the use of profiles and short drafts, and how to work out warp ends per profile square. It also covers double weaves with twill layers (1:2, 2:1, 2:2) and combinations of tabby with twill or basket in different blocks, illustrated by threading and tie-up drafts on every page.
