Using these ChiaoGoo RED Circular Needles is a breeze. First, choose the right size and length for your project. Thread your yarn onto the needle, and start knitting as you normally would. The smooth surface of the needle helps the yarn slide easily, making your knitting process faster. When you're done, gently remove the knitted piece from the needles. To keep your needles in great shape, avoid bending them too much as they are made of steel. Clean them with a soft, dry cloth regularly. Store them in a safe place, away from sharp objects that could scratch the smooth red nylon coating.
