A short article explaining Rep weave, a warp-faced corded structure made by alternating a heavy and a fine weft under a very closely set warp. It covers double-face fabrics in two colours, two-block patterns on two or four frames, transcribing Summer and Winter and crackle drafts into Rep, a single block on a plain background, and a variant with weft passing over two warp ends that gives three colour areas. Illustrated with threading drafts, profiles and fabric diagrams.
