A 1916 installment of Posselt's "A Study in Weave Formation" explaining imitation gauze weaves, also called mock-lenos or open-work effects. It describes how perforations arise from grouping warp and filling threads, with reed denting that leaves empty dents between groups. Weaves on 6, 8 and 10 harnesses are explained with drawdowns and fabric sketches, followed by figured effects that combine gauze and plain weaving in stripes or checks. The scan also includes a short unrelated item on South Africa's demand for silk ribbons.
