Using addi Turbo Circular Needles is a piece of cake. Just thread your yarn onto the needle and start knitting as you normally would. The nickel coating makes the yarn move easily, so you can work on your projects faster. When you're done with your knitting, store the needles in a dry place to prevent the nickel coating from getting damaged. Be careful with the non - standard sizing of the smaller needles. Always double - check the actual size against your pattern requirements. And since the US 36 and US 50 needle tips are plastic, avoid using excessive force to prevent breakage.
