Using these KnitPro Mindful Collection Fixed Circular Needles is easy. Just thread your yarn through the cable and start knitting as you normally would. For precision lace work, the stainless - steel tips will help you create detailed patterns. When using the cable as a ruler, simply align it with your work to measure. As for maintenance, keep the needles clean by wiping them with a soft cloth after use. Avoid bending the cables too forcefully to maintain their smoothness. Store them in a dry place to prevent rusting. And don't worry about the new packaging - the needles are still the high - quality tools you're used to.
