Using these KnitPro Mindful Collection Fixed Circular Needles is easy. Start by threading your yarn through the cable. The stainless - steel lace tips are great for getting into tight spaces when working on lace patterns. For everyday knitting, they'll work just as well, allowing you to create beautiful scarves, hats, or sweaters. When using the cables as a ruler, simply measure your work against the inch markings. As for maintenance, keep them in a dry place to prevent rust on the stainless - steel parts. After use, gently clean the needles with a soft cloth. Don't bend the cables too forcefully as it might damage them. Enjoy your knitting with these wonderful needles!
