A 1955 article from the Master Weaver newsletter that criticizes the confusing yarn-count systems used for cotton, linen, wool, silk and rayon in English-speaking countries. It lists old English yarn measures from the early 19th century and argues for the metric yarn number (meters per gram), with conversion factors and formulas between English counts and metric numbers. It also explains how to find an unknown yarn's metric number by weighing a one-meter sample and how to write plied yarns.
