Using these ChiaoGoo Knit RED Circular Needles is a breeze. First, pick the right size and length for your project. Slide the yarn onto the needle, and start knitting as you normally would. The smooth nylon - coated cable will help the yarn move easily. When you're done, be careful not to bend the needles, as they're made of steel and can lose their shape. To clean them, just use a soft, dry cloth. Store them in a safe place, away from other sharp objects that could scratch the smooth finish. This way, your needles will stay in great shape for all your future knitting adventures.
