Using your addi Turbo Circular Needles is a breeze. Just thread your yarn through the cord and start knitting. The smooth nickel coating helps the yarn glide, so you can work faster. When you're done, store the needles in a dry place to prevent the nickel coating from getting damaged. Be careful with the plastic needle tips on the US 36 and US 50 sizes - don't expose them to sharp objects or extreme heat. And remember, some of the smaller needle sizes are not standard US sizes, so double - check the label before starting your project.
