I-Cord is a round knit tube that can be made with as few as 2 stitches. You can use knitting needles, a spool, a loom, or a crochet hook tool to make it. But if you want to speed up the process, I highly recommend getting (or making!) an I-Cord maker. This handy little gadget is like a miniature knitting machine. In fact, it is made with knitting machine needles!
