A portfolio of mounted textile samples from Peru, issued as an accompaniment to Shuttle Craft Guild Monograph Twenty-Five by Harriet Tidball. It consists of a cover and photographs of swatches on colored cards, including ancient Chancay cotton fragments, modern Andean wool and alpaca weavings, edging tapes, and a strip of feathers. A caption page describes each sample's structure, fibers, origin and maker, including weft-face point-twill, floating-weft patterns and warp-stripe designs.
