Using these KnitPro Mindful Collection needle tips is easy. First, pick the cable you like, whether it's swivel or non - swivel. Then, screw the 5 - inch lace needle tips onto the cable. If you want to make a 16 or 20 - inch needle, make sure to use the 4 tips. As for maintenance, keep them clean by wiping with a soft cloth after use. Avoid dropping them to prevent damage. When storing, put them in a safe place to protect the delicate lace tips. And remember, even though the brand name has changed to KnitPro, the quality remains top - notch.
