Crochet is a process of creating fabric from yarn or thread using a crochet hook. The word is derived from the French word crochet, meaning hook. Crocheting, similar to knitting, consists of pulling loops of yarn through other loops. Crochet differs from knitting in that only one loop is active at one time (the sole exception being Tunisian crochet), and that a crochet hook is used instead of knitting needles.
