Cables, cords and connectors are used to join two interchangeable knitting needle tips together to create one longer length needle. This is useful for knitting large projects, such as blankets and sweaters. They are also used with Afghan/Tunisian crochet.
Cords and connectors come in a variety of materials, including plastic, metal, and wood. Swivel and fixed cords are available.
