Using these KnitPro Mindful Collection Fixed Circular Needles is a breeze. For detailed lace work, the stainless - steel lace tips help you make precise stitches. For regular knitting, they'll work just as well. When using the cables, since they're marked every inch, you can easily measure your work as you go. 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 dry place away from direct sunlight to prevent any damage. Remember, although the brand has changed from Knitter's Pride to KnitPro, the quality remains the same, so enjoy your knitting with these great tools!
