Using these ChiaoGoo RED Circular Needles is easy. First, pick the right size and length for your project. Then, start threading your yarn onto the needle. Since the cable is coated with smooth nylon, the yarn will slide smoothly, allowing you to knit quickly and easily. When using, be careful not to bend the needle too much as it's made of steel and can break under excessive force. After use, wipe the needles with a soft, dry cloth to keep them clean. Store them in a dry place to prevent rusting. Enjoy your knitting with these wonderful needles!
