Using these ChiaoGoo Knit RED Circular Needles is easy. First, choose the right size and length for your project. Start by threading your yarn onto the needle. As you knit, the smooth nylon - coated cable allows the yarn to slide easily. When you're done, gently remove the finished piece from the needles. To keep your needles in good shape, avoid bending them too much or using them on overly rough materials. You can clean them with a soft, dry cloth to maintain their smooth finish. Store them in a dry place to prevent rusting. With proper care, these needles will serve you well for many knitting projects.
