Using these ChiaoGoo Knit RED Circular Needles is a breeze. Start by threading your yarn through the cable and onto the needle. You can then begin your knitting project as usual. When you're done, gently remove the yarn. To keep your needles in good condition, avoid bending or dropping them. You can clean them with a soft, dry cloth. Store them in a cool, dry place, away from moisture and sharp objects. This will help maintain their smoothness and durability for many knitting projects to come.
