Using these addi Turbo circular needles is easy. Just thread your yarn through the cord and start knitting as you normally would. The smooth nickel coating helps the yarn move along effortlessly. When it comes to care, keep the needles clean and dry. Avoid using harsh chemicals as they might damage the coating. Store them in a dry place to prevent rusting. Remember to double - check the needle sizes as some don't follow the standard US sizing. If you're using the US 36 or US 50 needle tips, handle them gently as they're made of plastic and can break if dropped or bent too much.
