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 croc, which means 'hook'. Hooks can be
made from a variety of materials, such as metal, wood, bamboo, bone or
even 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.
