The Addi CraSyTrio knitting needles are purposefully designed for small, circular knitting projects that require a flexible needle. They can also be used as an alternative for the magic loop or double-pointed needles. When using the CraSyTrio needles, place your stitches over 2 needles and use the third for knitting on each side, making them ideal for creating your own socks, gloves, wrist warmers, cuffs or other small knitted project that are knitted in the round.
