Using these KnitPro Mindful Collection Fixed Circular Needles is a breeze. For any knitting project, whether it's delicate lace or your regular knitting, simply thread your yarn through the cable and start creating. When knitting, take advantage of the cable marked every inch to measure your work. The inspirational words on the needles can give you a little boost while you knit. As for maintenance, after each use, gently wipe the needles and cables with a soft, dry cloth to keep them clean. Store them in a cool, dry place to prevent any rusting. Also, be careful not to bend the cables too forcefully as this might damage them. Enjoy your knitting with these great needles!
