Using these KnitPro Mindful lace needle tips is easy. First, choose the cable that suits you, either with or without a swivel. Screw the 4'' US 3 tips onto the cable. You can use them to start your knitting project right away. Just note that if you want a 16 or 20 needle setup, make sure to use these 4 tips. As for maintenance, after each use, gently wipe the needles with a soft cloth to keep them clean. Store them in a dry place to prevent rust. Don't worry if your package comes with the KnitPro branding. It's still the great - quality tool you're used to.
