Peter Collingwood's book on handwoven rug techniques beyond basic plain weave, organized by structure. It covers weft-face rugs in plain weave (pick-and-pick stripes, crossed and clasped wefts, compensated inlay, weaving inscriptions), weft-face rugs in multishaft weaves (krokbragd, 2/2 twill, skip twills), and block weaves including three-end and four-end block drafts with pick-up and shaft-switching methods. Later chapters treat warp-face weaves, weft twining, rug finishes (braids, whipping) and workshop notes on loom features and equipment. Illustrated with many plates, diagrams and weaving drafts.

A reference collection of color-and-weave twill patterns for straight draw threadings on 2 to 8 harnesses, with over 1800 computer-generated drawdowns. The introduction explains how the number of distinct twills is counted (1 for 3 shafts, 2 for 4, 4 for 5, 14 for 6, 52 for 7, 320 for 8). Each treadling sequence is shown with several warp and weft color arrangements in black and white (W, B, BW, BWWB, BBWW and others). A closing section of photographs of woven samples refers back to the drawdown pages.
