A two-page article from Posselt's Textile Journal (August 1912) that works through the design and costing of a worsted trouserings fabric with spun silk stripes. It gives the warp dress, 33-end repeat, weave and drawing-in diagrams for a 14-harness fancy draw, reed calculations, selvage, filling and finishing details. It then calculates yarn quantities per yard and per 1000 yards, and ends with a method for finding warp length when several yarn counts are mixed, taken from Posselt's Textile Calculations.
