Ralph Griswold explains how to turn a fabric drawdown into a weaving draft by treating the drawdown as a rectangular array of zeros and ones. Counting the distinct rows gives the number of treadles, and counting the distinct columns gives the number of shafts. The article gives short Icon programs that compute loom requirements and produce the threading, treadling and tie-up, and a longer program that outputs a WIF file. It also covers deriving drafts from black-and-white images, with a 65 by 65 pixel Japanese pattern that needs 32 shafts and 32 treadles as an example. Appendices contain the program listing, sample WIF output and the image example.
