Using your addi Turbo Circular Needles is easy. First, thread your yarn onto the needle and start knitting as you normally would. The nickel coating helps the yarn move smoothly, so you can focus on your pattern. When you're done with your project, gently remove the finished piece from the needles. To keep your needles in good condition, avoid bending the cords too sharply and store them in a dry place. Be aware of the non - standard sizing of some of the smaller needles, and remember that the US 36 and US 50 tips are plastic, so handle them with care to prevent breakage.
