A question-and-answer column by Mary M. Atwater from The Weaver, July 1936. It explains how to calculate yarn quantities from yarn counts (linen cut of 300 yards, cotton and wool hank of 840 yards), with worked examples for warp yardage and advice on estimating weft and allowing for waste. Shorter answers cover applying warp dressing and where to get gauge-bars and knives for knotted pile rugs. The page also carries the concluding paragraphs of an article on a wall hanging woven in a tapestry-like technique on a rosepath threading with a binder.
