Second article in a Master Weaver series on turned twills, focusing on how to design the tie-up. It explains making a short tie-up draft from the pattern profile, choosing matching pairs of 1:2 and 2:1 twill tie-ups (and 1:3, 1:4, 1:5), and exchanging vertical lines of ties to derive alternatives. It ends with limits on the number of blocks and treadles possible on 8-, 12- and 16-shaft looms.
