A one-page Questions and Answers column by Mary M. Atwater on calculating yarn quantities for weaving. It works through an overshot coverlet in two strips, figuring warp yardage from the cotton count (24/3 at 6,720 yards per pound) and weft weights for Shetland pattern yarn and cotton tabby. It also gives a tweed example and the base yardage figures for cotton, wool (840) and linen (300).
