A single-page installment of E. A. Posselt's series on fabric analysis, introducing what a complete analysis of a textile involves: weave, materials, texture, yarn counts and twist, weight per yard, and dyeing and finishing. It then explains how to find a fabric's weight per yard. The method is to trim a sample to a known size with cardboard guides, a compass or a steel cutter, including a cross-shaped cutter that gives 2 square inches, and then to weigh it on a delicate balance. Worked examples convert grains to ounces per yard. The text ends with a note that it continues on page xii.
