The word crochet comes from the French word for hook. Crochet is a method of weaving strands of material into patterns. It differs from needlework in that crochet uses one hook and needlework uses 2 needles. The earliest crochet-like work probably goes back to ancient times when a finger was used instead of a hook. Crochet was definitely known to have been done in the Renaissance times and became especially popular in the 1800s continuing to present times. Classical crochet uses yarn or similar fabric strands. Crafters began crocheting beads onto bags and clothing in the 1800s using yarn and other classical crochet fabrics. Recently jewelry artists have begun using silver and other precious metals to crochet beads into necklaces, bracelets, and other jewelry.
