Using these addi Turbo circular needles is easy. Just thread your yarn through the needle tip and start knitting as you normally would. The smooth nickel coating will help the yarn move freely, so you can work faster. When you're done with your project, gently remove the needles from the yarn. To keep your needles in good condition, avoid dropping them on hard surfaces as this could damage the coating or the tips. You can clean them with a soft, dry cloth to remove any lint or debris. Remember the special sizing of the smaller needles and that the US 36 and US 50 tips are plastic, so handle them with a bit of extra care.
