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 these needles away from sharp objects to avoid scratching the coating. You can clean them with a soft, dry cloth. Remember, some of the smaller sizes don't follow the standard US sizing, so double - check before starting your project. And be gentle with the plastic tips on the US 36 and US 50 needles to prevent breakage.
