Using these ChiaoGoo double pointed needles is a breeze. Just thread your yarn onto the needle tip and start knitting as you normally would. When you're working on your project, make sure to keep the needles in a safe place to avoid bending or losing them. To maintain these needles, simply wipe them with a soft cloth after each use. Avoid using abrasive materials that could scratch the satin - sheen finish. Since they're made of stainless steel, they're quite resistant to rust, but it's still a good idea to store them in a dry environment. If you have any extra needles, you can group them together by size and keep them organized in a knitting case. Enjoy your knitting with these high - quality needles!
