Using these KnitPro Mindful Fixed Circular Needles is easy. Just pick up your yarn and start knitting as you normally would. The lace tips are great for intricate lace patterns, but they work well for all kinds of knitting projects. When you're knitting, the inch - marked cables can help you measure your work easily. As for maintenance, keep them in a dry place to avoid rusting. Don't bend the cables too much to keep them free from kinks. If they get dirty, you can gently wipe them with a soft cloth. Remember, even though the brand has changed to KnitPro, the quality remains top - notch.
