The word crochet is derived from the French word crochet, a diminutive of croche, in turn from the Germanic croc, both meaning "hook". It was used in 17th-century French lace-making, where the term crochetage designated a stitch used to join separate pieces of lace. The word crochet subsequently came to describe both the specific type of textile and the hooked needle used to produce it. Crochet is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread, or strands of other materials. The name is derived from the French term crochet, which means 'hook'. Hooks can be made from different materials (aluminum, steel, metal, wood, bamboo, bone, etc.), sizes, and types (in-line, tapered, ergonomic, etc.). The key difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before the next one, while knitting keeps many stitches open at a time. Some variant forms of crochet however, such as Tunisian crochet and Broomstick lace, do keep multiple crochet stitches open at a time.
