Using these addi Turbo Circular Needles is a breeze. Just thread your yarn onto the needle and start knitting as you normally would. The smooth nickel coating will help the yarn move easily. When it comes to maintenance, simply wipe the needles with a soft cloth after use to keep them clean. Store them in a dry place to prevent rust. Be aware of the non - standard sizing of some smaller needles and the plastic tips of US 36 and US 50 needles. Don't use excessive force on the plastic tips to avoid breakage. With these tips, you'll enjoy a great knitting experience with your addi Turbo needles.
