Using these ChiaoGoo Knit RED Circular Needles is easy. First, choose the right size and length for your project. Then, simply start knitting as you normally would, and enjoy how the smooth nylon - coated cable lets the yarn slide easily. When you're done with your knitting session, store the needles in a dry place to prevent rusting. To clean them, you can use a soft cloth to wipe off any dirt or lint. Avoid using harsh chemicals as they might damage the nylon coating. With proper care, these needles will last you through many knitting projects.
