Using these KnitPro Mindful Collection Fixed Circular Needles is easy. Just thread your yarn through the cable and start knitting. For precision lace work, use the stainless - steel lace tips to create intricate patterns. For everyday knitting, the smooth cables ensure a hassle - free experience. When using the cables as a ruler, simply measure your work against the inch markings. As for maintenance, keep the needles and cables clean by wiping them with a soft, dry cloth after use. Store them in a dry place to prevent rusting. And don't worry if you receive them in the new KnitPro packaging - the quality remains the same!
