Using these ChiaoGoo Knit RED Circular Needles is a breeze. Start by choosing the right size and length for your project. Thread your yarn through the cable and onto the needle tip. As you knit, the smooth nylon - coated cable will help the yarn slide easily. When not in use, store them in a dry place to prevent rusting. Avoid dropping them on hard surfaces as this could damage the tips. Clean them gently with a soft cloth if they get dirty. With proper care, these needles will serve you well for many knitting projects.
