An introductory article on how to draft double weaves, in which two layers of cloth are woven at once. It explains independent, stitched and pattern-penetrating layers, and why four symbols are needed for warp and weft in threading, treadling and draw-downs. Worked examples cover double tabby and double twill on 4 to 6 frames, treadling for double-width and circular fabrics, and ways to stitch the layers together using tie-up changes, a stitching treadle or an extra heddle frame. Figures 1-19 show the tie-ups, threadings and draw-downs.
