Two-page article from Posselt's Textile Journal, February 1920, explaining how to calculate yarn counts from cloth samples. It gives tables of standard weights and lengths for worsted, cotton, silk, linen, ramie and woolen yarn systems, with worked examples for each. It also covers converting cotton yard counts to metric counts and converting denier counts of artificial silk to cotton or spun silk counts. The pages end with a short news item on a drop in wool consumption and a note on a dye bath for a blue-black shade.
