Using these ChiaoGoo Knit RED Circular Needles is a breeze. Start by choosing the right size and length for your project. Simply thread your yarn onto the needle and begin knitting as you normally would. The smooth red nylon coating on the cable makes it easy for the yarn to move around. When you're done, gently remove the finished piece from the needles. To keep your needles in good shape, store them in a dry place. Avoid bending or dropping them, as this could damage the stainless - steel construction. If they get dirty, you can wipe them with a soft, dry cloth.
