These ChiaoGoo double pointed needles are super easy to use. Just start by threading your yarn through the eye of the needle. You can use them for knitting small circular projects like socks, mittens, or hats. When you're done knitting, avoid bending the needles too much as they're strong but can still be damaged. To keep them in top shape, wipe them with a dry cloth after each use. Store them in a dry place, away from moisture to prevent rusting. They're 100% recyclable, so when they're no longer usable, you can recycle them properly.
