Using these ChiaoGoo RED Circular Needles is a breeze. Start by threading your yarn through the cable, then pick up your stitches as you normally would. Because the yarn slides easily on the smooth nylon - coated cable, you can work on your knitting project with less effort. When you're done knitting, gently remove the yarn from the needles. To keep your needles in great shape, avoid bending them forcefully. You can clean them with a soft, dry cloth to remove any dust or lint. Store them in a cool, dry place, away from direct sunlight to prevent the nylon coating from fading.
