The self-instructor in textile designing; or, A practical guide in designing & weaving
A self-instruction manual on textile design and weaving by Amos A. Baldwin, published in Brasher Falls, New York, in 1890 for home weavers and students learning to plan cloth structures. Its pictures are small grid diagrams of weave drafts, with filled and empty squares showing how threads interlace, and a designer could take from them the repeating geometric patterns of simple woven textiles such as checks, twills and diamonds.
