Kolláge Firm Cables are designed to be ergonomically suited to your hands, decreasing stress and strain for those who love to knit. The square shape enables you to knit faster with more uniform stitches. They are perfect for slippery yarns or if you knit tightly, and for knitters who have arthritis, carpal tunnel or stiffness in their hands and fingers. The cables are flexible yet firm enough to carry your stitches quickly and easily over the needle tips. The swiveling join means your cords won’t get twisted as you knit! They are beloved by fast knitters, those who knit heavier projects, and knitters who knit in the round on 2 circular needles.
