Using these KnitPro Mindful Fixed Circular Needles is easy. Just thread your yarn through the cable and start knitting as you normally would. For precision lace work, the lace tips will help you make detailed stitches. The cable markings can be used to measure your work as you go. When it comes to maintenance, keep the needles away from sharp objects to avoid scratching the stainless - steel. After use, store them in a dry place to prevent rust. If the needles get dirty, you can gently wipe them with a soft cloth. And don't worry if you receive the product in the new KnitPro packaging; the quality remains the same.
