Using these KnitPro Mindful Collection Fixed Circular Needles is a breeze. Just pick up the needle and start your knitting project as you normally would. They're great for lace work and regular knitting. When using the cable as a ruler, simply align it with your work to measure. As for maintenance, keep them in a dry place to prevent rusting. Avoid bending the tips too much as they're designed for precision. If they get dirty, you can gently wipe them with a soft cloth. When the KnitPro package arrives, don't be confused by the new name. It's the same great product you ordered, just with a fresh look.
