Using these addi Turbo Circular Needles is a breeze. Just thread your yarn through the cord 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 from the needles. To keep your needles in good shape, store them in a dry place away from sharp objects that could scratch the coating. Be aware of the non - standard sizing for some of the smaller needles and the plastic tips on US 36 and US 50. This way, you'll have a great knitting experience every time.
