An International Correspondence Schools instruction paper on designing weaves for backed cotton fabrics, in which an extra warp or filling adds weight or warmth without showing on the face. It covers filling-backed and warp-backed cloths, including how to arrange face and back picks or ends, place the tying points, and make harness and chain drafts. The last sections treat piqués and Bedford cords, with wadding picks or ends, cutting picks and instructions for dissecting these cloths. Many design-paper figures and practice problems are included.
