Part 7 (1901) of Charles G. Petzold's serial textbook on weave construction for textile schools, designers, overseers and loom fixers. It covers honeycomb weaves, several methods of building granite weaves (from plain and rep, sateen with added binders, cross twill with lines removed, and broken twill parts), and Mockel's weaves with four changes built on twill and sateen foundations. It closes with a section on how regular and reversed yarn twist affects light and shade in plain, sateen and twill fabrics, illustrated with photographs. Figures 451-624 are drawdown-style grids, and the issue includes advertisements for Lawrence, Mass. mill suppliers.
