A practical treatise on weaving and designing of textile fabrics : with chapters on the principles of construction of the loom, calculations, and colour
A practical treatise on weaving and textile design by Thomas R. Ashenhurst, published in Huddersfield, England, in 1885, aimed at weavers and designers working with looms and fabric construction. The pictures are line diagrams of warp threads running over harness and healds, plus ray diagrams showing how weft and shuttle paths cross, drawn in plain black ink with lettered reference points. A designer could take from them the clean schematic style of technical drawing and the way crossing lines can explain structure.
