Part No. 6 of Charles G. Petzold's serial textbook on the construction of weaves for textile schools, designers, overseers and loom fixers. It covers drafting and the reduced draft, classes of drafts (straight, point or diamond, broken, stepping-up, section, two-division, irregular and mixed), and calculating harness eyes per inch. It also gives a tartan plaid dressing plan and the construction of checkerboard, ray-like and honeycomb weaves from twill, sateen, rep and basket foundations. Most pages carry numbered drawdown figures (about 347 to 450), and the issue includes advertisements for Lawrence, Mass. loom and mill suppliers.
