Using your 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 the needles effortlessly. When it comes to care, keep them in a dry place to prevent the nickel coating from rusting. Be gentle with the cords as they are pliable but can be damaged if bent too forcefully. Remember the special sizing of the smaller needles, so you pick the right one for your project. Also, handle the plastic tips of the US 36 and US 50 needles carefully to avoid scratches or breakage.
