Using these KnitPro Mindful Collection Fixed Circular Needles is easy. First, choose the yarn you want to use and start by casting on stitches onto the needles. Since the cables are marked every inch, you can easily measure your work as you go. When knitting lace patterns, the stainless - steel lace tips will help you make precise stitches. As for maintenance, keep the needles clean and dry. After use, store them in a cool, dry place. Avoid bending the cables too harshly to prevent any damage. Also, don't worry if your product arrives in the new KnitPro packaging; the quality remains the same.
