An instructional article from Posselt's Textile Journal introducing the foundation weaves for textile designers: plain weave, twills and satins. It explains the repeat of a weave, plain weave construction and cord/repp effects, and then twills on 3, 4, 5 and 6 harnesses, with interlacing diagrams and point-paper drafts. The final page also carries a worsted trousering fabric specification (reversible stripe) with warp arrangement, reed, filling and finish details. The article is marked to be continued, and the satin section is not reached in these pages.
