A fourth-edition French textbook on weaving silks and ribbons, by J. Seillon, a weaving teacher in Saint-Étienne. It opens with a glossary of trade terms, then covers textile materials (silk, cotton), warping, drafting and the basic weaves such as satin, twill and taffeta. The main body treats ribbon types: figured taffetas, gauze, brocaded, pile, fringe, picot, guipure and crêpe. Later sections cover Jacquard and tambour looms, dyeing arrangements, cost-price calculations, colour harmony and silk-count tables. About 20 plates of weave drawdowns (point-paper diagrams) in black and red close the volume.
