Two pages from Textiles (vol. 15) containing part 4 of E. Bittner's series on the construction of weaves, which covers motifs developed with 3-leaf warp and filling twills and their color effects (Figs. 549-550f). The same pages also carry a section of John Reynolds's 'The Practical Fixing of Cotton Looms', on timing the still box motion and adjusting the 6 and 1 box motion.
