Using addi Turbo Circular Needles is easy. First, select the right needle size for your yarn and project. Then, start knitting as you normally would, and enjoy how the nickel - coated surface lets the yarn glide. When using the needles, be aware of the non - standard sizing for some smaller needles as mentioned. After use, gently clean the needles with a soft cloth to keep them in good condition. Store them in a dry place to prevent any damage to the cords or tips. If you're using the plastic tips of US 36 and US 50, handle them with care to avoid breakage.
