Using these ChiaoGoo double pointed needles is a breeze. Start by threading your yarn through the tip of the needle. You can use them for various knitting projects like making socks, mittens, or small hats. When knitting, hold the needles firmly but not too tightly to let the yarn move freely. To avoid bending the needles, don't force the stitches. After use, gently wipe the needles with a soft, dry cloth to keep them clean. Store them in a needle case to prevent any damage. And remember, since they're recyclable, when they reach the end of their useful life, you can dispose of them in an eco - friendly way.
