Using these ChiaoGoo double pointed needles is a breeze. Just start by threading your yarn onto one of the needles. You can use them for knitting small - diameter items like socks, mittens, or the sleeves of a sweater. When you're done knitting, be careful not to bend the needles as they're thin and can get damaged easily. To keep them in good condition, simply wipe them with a soft, dry cloth after each use. Store them in a needle case to prevent them from getting lost or dulling the tips. And remember, since they're recyclable, you're making an eco - friendly choice too!
