Part of a serial article from Posselt's Textile Journal explaining how skip twills are constructed from even-sided foundation twills. It gives the rule for choosing groups of warp threads and for working out how many harnesses to skip, and describes Figs. 1-11 (4-, 6- and 10-harness foundations, with stripe effects, alternating group sizes and broken skip twills). The second page also begins a separate article on Jacquard point-paper designing, with a diagram of the straight-through tie-up of a 400 Jacquard machine.
