A single-page article from Posselt's Textile Journal, March 1915, explaining how to construct 75-degree diagonal weaves from regular 45-degree twills by taking every fourth warp thread of the foundation twill. It gives worked examples (24-, 36- and 34-harness foundation twills) and describes a plate of six diagonals (Figs. 1-6) with their repeats, plus how to work back from a diagonal to its foundation twill. It follows an earlier January article on 70-degree diagonals.
