A one-page technical note from the Master Weaver Information Service on weaving several colours in one row of Summer-and-Winter. It explains how many colours a given number of shafts allows, how weft shots are ordered across blocks, and why more colours make clean block colour harder to achieve. Four draw-down figures illustrate bound weave versus multicolour treadling, with advice on weft and warp choice, colour contrast, and carrying all colours through the whole pattern.
