Using these ChiaoGoo Knit RED Circular Needles is easy. First, choose the right size and length for your project. Thread your yarn onto the needle and start knitting as you normally would. The smooth red nylon coating on the cable makes it a breeze for the yarn to move. When it comes to maintenance, simply wipe the needles with a clean, dry cloth after use to keep them in good condition. Avoid using harsh chemicals as they may damage the nylon coating. Store the needles in a dry place to prevent rusting. And always handle them gently to keep the blunted tips in shape.
