A French-language plate atlas of about 3,800 numbered weave structures (armures) by Louis Serrure, a former weaving teacher at the Roubaix school, with a preface by Jean Pilisi. The plates are arranged by the number of shafts or threads in the repeat, from plain weaves on 2 and 3 shafts up to 72 threads. Later plates cover épinglé (epingline), warp and double-face weaves, ecorce (bark) weaves, drap weaves, double cloth and Ottoman-pattern pointing. Each drawdown is numbered and labeled with warp and weft repeat sizes. The book is almost entirely drawdown grids with very little text.
