A three-volume compilation by Ralph Griswold of over 12,000 (the text also says 13,000 and 15,000) weave patterns drawn from old, copyright-free weaving and textile design books. The patterns are shown as black-and-white drawdown grids, grouped by number of ends (4 to 96) and then by number of picks, and roughly ordered by structural complexity. The front matter explains how the patterns were reduced to unit motifs, rotated, and de-duplicated, lists the source books, and gives appendices on structural complexity, how the collection was built, and copyright of patterns. Volume 1 covers 4 to 12 ends, Volume 2 covers 13 to 16 ends, and Volume 3 covers 17 to 96 ends.
