Using these addi Turbo Circular Needles is easy. Just thread your yarn onto the needle and start knitting as you normally would. The smooth nickel coating helps the yarn move freely, so you can work quickly. When using, be aware of the non - standard sizing for some smaller needles as mentioned. After use, gently wipe the needles with a soft cloth to keep them clean. Store them in a dry place to prevent any damage to the coating or cords. Don't bend the cords too harshly as they are flexible but can break if over - stressed.
