Using your ChiaoGoo RED Lace Circular Needles is a breeze. First, pick the right size and length for your project. Thread your yarn through the cable and start knitting as you normally would. The smooth surface of the needles and the red nylon - wrapped cable will make the yarn glide easily. When it comes to maintenance, simply wipe the needles with a soft, dry cloth after each use to keep them clean. Avoid using harsh chemicals as they may damage the finish. Also, remember that the US 17 needles have a non - standard size, so double - check your pattern requirements. Store your needles in a dry place to prevent rusting, and they'll serve you well for many knitting projects to come.
