Using these KnitPro Mindful Collection needle tips is easy. First, select the cable that suits your needs. You can choose a swivel or non - swivel cable according to your preference. Then, simply screw the 4'' US 9 lace needle tips onto the cable. When making a functional 16 or 20 needle, remember to use the 4'' tips. As for maintenance, keep your needles clean. You can wipe them with a soft cloth after use. Store them in a dry place to prevent rust. Don't worry if your order arrives in a KnitPro package; it's still the great - quality product you know.
