Using your ChiaoGoo RED Lace Circular Needles is a piece of cake. Just thread your yarn through the cable and start knitting as you normally would. The smooth surface and pointy tips make it easy to pick up stitches and create beautiful patterns. When it comes to maintenance, keep your needles clean by wiping them with a soft, dry cloth after each use. Avoid using harsh chemicals or abrasive materials as they can damage the nylon coating. Also, store your needles in a dry place to prevent rusting. Remember, the US 17 needles have a non - standard size, so double - check your pattern requirements if you're using them. With proper care, these needles will serve you well for many knitting projects to come.
