Crochet is a process of creating fabric by interlocking loops of yarn, thread, or strands of other materials using a crochet hook. The name is taken from the French word "crochet", meaning small hook. These are made of materials such as metal, wood, or plastic and are manufactured commercially and produced in artisan workshops. The salient difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before proceeding with the next one, while knitting keeps a large number of stitches open at a time. (Variant forms such as Tunisian crochet and broomstick lace keep multiple crochet stitches open at a time.)
The word crochet comes from the Old French crochet, a diminutive of croche, in turn from the Germanic croc, all meaning "hook". It was used in 17th-century French lace making, crochetage designating a stitch used to join separate pieces of lace, and crochet subsequently designating both a specific type of fabric and the hooked needle used to produce it. Although that fabric is not known to be crochet in the present sense, a genealogical relationship between the techniques sharing that name appears likely.
