Using your addi Turbo Circular Needles is easy. First, choose the right size needle for your project, keeping in mind the sizing differences mentioned. Thread your yarn onto the needle and start knitting as you normally would. The smooth nickel coating will help the yarn move easily. When you're done with your project, gently remove the needles from the yarn. To maintain your needles, keep them in a dry place and avoid bending the cords too much. If they get dirty, you can wipe them with a soft, dry cloth. Be careful with the plastic tips on the US 36 and US 50 needles as they may break if handled roughly.
