Using these Addi Turbo circular needles is a breeze. Simply thread your yarn through the needle tip and start knitting as you normally would. The smooth nickel coating helps the yarn move easily, so you can work faster. When you're done with your project, gently remove the yarn. To keep your needles in good condition, store them in a dry place away from sharp objects that could scratch the coating. Remember, some of the smaller sizes have non - standard US sizing, so double - check the label before starting your project. And be careful with the plastic tips on the US 36 and US 50 needles as they can break if mishandled.
