Using your addi Turbo Circular Needles is super easy. Just thread your yarn through the needle and start knitting as you normally would. The nickel coating helps the yarn move smoothly, so you can work faster. When you're done with your project, make sure to store the needles in a dry place to prevent the nickel coating from getting damaged. Since some of the smaller needle sizes don't follow standard US sizing, always double - check the actual size before starting your project. Also, be gentle with the plastic needle tips of the US 36 and US 50 needles to avoid cracking them.
