Using these KnitPro Mindful double point needles is a breeze. For sock, hat, or sleeve knitting, start by casting on your stitches on one or more needles. Then, begin knitting in the round, moving from one needle to the next. Remember to keep your tension even for a nice, uniform look. As for care, avoid using abrasive cleaners that could scratch the stainless steel lace tips. After use, simply wipe the needles with a soft, dry cloth and store them in a cool, dry place. When you're not using them, keep them in the provided eco - friendly packaging to protect them. If you notice any loose parts or damage, don't use the needles and contact customer service.
