These flexible silicone hollow cords are perfect for trying on your in-progress knitting projects without removing any of them from your needles! The end of the cord squishes firmly over most size needles, from US 0 (2mm) to US 15 (10mm). After it is attached to your needle tip, simply slide stitches onto the flexible tubing so you can try your garment on. When you are done, push all of the stitches back onto the needle and pull off the tubing. Great for trying on smaller accessory items like hats, gloves/mittens, socks, etc. Each pack comes with 3 cords (minimum 24", up to 32" length, and each may be different). These can be cut to make them smaller if need be. Comes in a secure screw-top circular tin, with a window for quick and easy viewing.
