Using these ChiaoGoo Knit RED Circular Needles is a breeze. First, pick the right size and length needle for your project. Start by threading your yarn onto the needle, and then begin your knitting stitches as you normally would. The smooth surface of the needles and the nylon - coated cable make it easy for the yarn to move. When you're done knitting, be careful not to bend the needles as they're made of steel. To clean them, simply wipe with a soft, dry cloth. Store them in a cool, dry place to keep them in good condition. Avoid using them on rough surfaces as it might damage the nylon coating.
