An instructional article from Master Weaver on cross-weaves (gauze, leno, pickets and riddles) for handweavers on four-shaft looms. It explains why cross-weaves allow very open warp setts, defines the terms, and surveys four methods of crossing warp ends. It then details the doup-without-standards method: making the doups, threading, tie-up, treadling sequences, and adjusting the sheds, including adding a spring-loaded roller to lengthen the warp ends. Diagrams show the crossings, the threading and the tie-ups.
