Using these ChiaoGoo Knit RED Circular Needles is a breeze. First, choose the right size and length for your project. Start by casting on your stitches as you normally would. The smooth red nylon - coated cable helps the yarn slide easily, so you can work quickly and efficiently. When not in use, store the needles in a dry place to prevent rusting. Avoid using them with overly rough or abrasive yarns that could damage the smooth finish. If the needles get dirty, you can gently wipe them with a soft, dry cloth. That's all you need to know to keep these needles in great shape and enjoy your knitting.
