Using these ChiaoGoo Knit RED Circular Needles is easy. Start by choosing the right size and length for your project. Thread your yarn onto the needle and begin knitting as you normally would. The smooth nylon - coated cable allows the yarn to move freely, so you can work quickly and efficiently. When not in use, store your needles in a dry place to prevent rusting. Avoid using them on very rough or abrasive yarns as this may damage the nylon coating. To clean, simply wipe them with a soft, dry cloth. With proper care, these needles will serve you well for many knitting projects.
