Using these KnitPro Mindful Collection interchangeable lace needle tips is a breeze. First, choose the cable you like. The tips are compatible with any KnitPro cable. You can go for a swivel or non - swivel cable according to your knitting style. To make a functional 16 or 20 needle, make sure to use the 4'' tips. When you're done knitting, gently clean the needle tips with a soft cloth. Keep them in a dry place to prevent rusting. Don't worry if your product arrives in a KnitPro package as it's just a new name and packaging, and the quality is still top - notch.
