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 'hook'.
Hooks can be made from a variety of materials, such as metal, wood,
bamboo, bone 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.
