A pattern book by Ralph Griswold presenting thumbnail drawdowns of computer-generated crackle weave designs, each labeled with the number of its downloadable WIF file at handweaving.net. The patterns come from a program that randomly varies motif, tie-up, and path, and are grouped by shape (square, wide, tall) and then by size, from about 92 x 92 up to 599 x 599. A short introduction explains the method and cites Griswold's three-part Crackle Weave series.
