Using addi Turbo Circular Needles is super easy. First, pick the right size needle for your project according to the yarn thickness. Slide the yarn onto the needle, and start knitting as you normally would. The smooth nickel coating will help the yarn move along effortlessly. When you're done with your project, store the needles in a dry place to avoid rusting on the coated parts. Be careful with the smaller sized needles as their labeled sizes may not match the standard US sizing. And since the US 36 and US 50 needle tips are plastic, handle them gently to prevent breakage.
