Crochet thread

Crochet thread produces fabric of fine gauge that may be stiffened with starch.

Crochet thread is almost always produced from cotton and has a denser pile and smaller diameter than ordinary yarn.

Crochet thread can withstand considerable stresses from pulls with sharp hooks.

Crochet manufacturing conventions treat thread and yarn quite differently: manufacturers designate different sizing scales for thread and yarn.

Smaller sizes (40 and up) are often used for tatting jewelry and fine lace.
