These ChiaoGoo double pointed needles are super easy to use. Start by threading your yarn onto the needle tip and then begin your knitting stitches. They're great for making small circular projects like socks or mittens. When using, don't pull the yarn too tightly as it might bend the needles slightly. To clean them, simply wipe with a soft, dry cloth. Store them in a needle case to avoid any damage. They're made of recyclable material, so when you're done with them, make sure to recycle properly.
