A two-part web article, edited by Brian Lemin, on how to identify the materials of lace bobbins, tatting shuttles, crochet hooks and other handwork tools, and of fabrics and threads. Part One covers bone versus ivory, plus Bakelite, celluloid, tortoiseshell, horn and plastic, using visual checks, hot-needle and match tests, and smell. It includes letters and notes from contributors and a short history of early plastics. Part Two covers fabric and fibre identification (cotton, linen, wool, silk, rayon, acetate, polyester, nylon, acrylic) by look and feel, break, burn, microscopic and chemical tests.
