Using these ChiaoGoo Knit RED Circular Needles is a breeze. First, pick the right size and length for your project. Thread your yarn onto the needle and start knitting as you normally would. The smooth nylon - coated cable makes it easy for the yarn to move, so your knitting process will be smooth. When you're done knitting, store the needles in a dry place to prevent rusting. Avoid using excessive force while knitting as it might damage the needles. To clean them, simply wipe with a soft, dry cloth.
