Using these ChiaoGoo double pointed needles is a breeze. Start by threading your yarn onto one of the needles. You can then begin knitting your project, whether it's a small scarf or a cozy hat. When you're done, simply remove the knitted item from the needles. As for maintenance, keep them away from sharp objects to avoid scratching the satin - sheen finish. You can clean them with a soft, dry cloth. And remember, since they're recyclable, when it's time to part with them, you can do so in an eco - friendly way.
