Using these ChiaoGoo RED Lace Circular Needles is a breeze. Just thread your yarn through the smooth red - nylon - wrapped cable and start knitting your favorite patterns. For best results, keep your needles clean by gently wiping them with a soft cloth after each use. Avoid using abrasive materials that could scratch the stainless - steel surface. When not in use, store the needles in a dry place, away from moisture to prevent rusting. And remember, the US 17 needles have a non - standard size, so double - check your pattern requirements if you're using them.
