An article from Shuttle-Craft Bulletin's "Multiple-Harness Weaver" series introducing the idea of basic drafts for eight-harness looms. It reviews the versatility of the four-harness twill and its shed combinations, then extends the principle to eight-harness threadings. The main example is the four-block opposites threading (1,2,1,2; 3,4,3,4; 5,6,5,6; 7,8,7,8), with a draft and a woven sample of alternating tabby and basket-weave blocks, suited to blankets.
