Part 3 (July 1900) of Charles G. Petzold's serial textbook on the construction of weaves, intended for textile schools, designers, overseers, loom fixers and webdrawers. It covers sateen weaves (including sateens with additional binders), diagonal rep and corkscrew weaves, reps with coarse and fine ribs, reps in broken and undulated lines, reps with increasing and decreasing floats, and chevron, cross and herringbone twills. Most pages are drawdown grids (figures 181-259) with rules for step-numbers and for calculating harness and pick counts. It includes woven portraits of Goethe and Columbus and trade advertisements for Lawrence, Mass. mill suppliers.
