Using these ChiaoGoo Knit RED Circular Needles is a breeze. Just thread your yarn onto the needle and start knitting as you normally would. The smooth red nylon - coated cable helps the yarn slide easily, so you can work faster. When using, avoid using excessive force as the needles are high - quality but still need proper care. After you finish your project, gently clean the needles with a soft cloth to remove any lint or debris. Store them in a dry place to prevent rusting. And don't worry about losing them, you can keep them organized in a knitting needle case.
