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, sizes, and types. The key difference between crochet and knitting, beyond the implements used, 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.
