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, meaning 'small hook'. Hooks can
be made from a variety of materials, such as metal, wood, bamboo, or
plastic. 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 is begun, while knitting keeps many stitches
open at a time. Some variant forms of crochet, such as Tunisian crochet
and broomstick lace, do keep multiple crochet stitches open at a time.
