Section 1 of Terrace Textures, a 1949 series of handweaving lessons from the Terrace Yarn Shop in Portland, Oregon. It teaches design principles (rhythm, color harmony, neutrals, proportion, dominance) through woven samples, mostly twill threadings on a standard tie-up. Each sample gives yarn type and size, warp set, amounts, reed setting, treadling and finishing for projects such as place mats, towels, suiting and coating, upholstery, aprons, baby blankets and a handbag. The final lesson introduces a bowknot loop technique. Linen, cotton and wool yarns are covered, with a few short threading drafts for herringbone, lace and basket-weave variations.
