A browsing index of the weave structures (armures) in Louis Serrure's Atlas de 4000 Armures, one of the largest pattern books. Ralph Griswold derived small black-and-white drawdown thumbnails from the WIF files digitized by Kris Bruland. The thumbnails are grouped by repeat size, width first, from 2 x 2 up to 80 x 40. Each is labeled with the number of its WIF file on handweaving.net. A short introduction explains the organization and says the material may be used for individual projects but not republished.
