Using these ChiaoGoo Knit RED Circular Needles is easy. Just start by threading your yarn onto the needle. The smooth nylon - coated cable will help the yarn slide smoothly as you work on your knitting. When you're done with your project, simply remove the yarn. To keep your needles in great shape, avoid bending them too forcefully as they're made of steel. Clean them with a soft, dry cloth occasionally to remove any dust or lint. Store them in a dry place away from moisture to prevent rusting. Whether you're a beginner or an experienced knitter, these needles will be a great addition to your knitting toolkit.
