Using these ChiaoGoo double pointed needles is a breeze. Just start by threading your yarn onto the needle. You can use them for various knitting projects like making socks, hats, or small amigurumi. When you're done knitting, be careful not to bend the needles as they're thin and could get damaged. To keep them in top shape, wipe them with a dry cloth after each use. If they get a bit dirty, you can gently wash them with mild soap and water, then dry them thoroughly. Since they're made of stainless steel, they're resistant to rust, but it's still best to store them in a dry place. Enjoy your knitting with these great needles!
