Using these addi Turbo circular needles is a breeze. Just thread your yarn through the needle and start knitting as you normally would. The smooth nickel coating helps the yarn move easily, so you can work quickly. 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. Be aware that some of the smaller needle sizes don't follow the standard US sizing, so double - check the actual size before starting your project. Also, since the US 36 and US 50 needle tips are plastic, handle them with a bit of care to avoid any breakage.
