A short article from Master Weaver explaining the tie-up as a logical part of a weaving draft, distinguishing the "theoretical" tie-up from the "practical" one actually used. It covers standard tie-ups for counterbalanced four-harness looms, the three-part tie-up of spot weaves such as Summer and Winter, and tie-ups for diamond twills, turned twills and four-block double weave. It ends with how tie-ups are rearranged when a loom has too few treadles. Illustrated throughout with tie-up diagrams.
