Using these addi Turbo Circular Needles is a breeze. Start by threading your yarn through the cord and onto the needle tip. Then, simply begin your knitting as you normally would. The smooth nickel coating helps the yarn move easily, so you can work quickly. When it comes to sizing, double - check the actual size as some don't follow the standard US scale. For maintenance, keep the needles clean by wiping them gently with a soft cloth. Avoid bending the cords too sharply to keep them flexible. Store the needles in a dry place to prevent any damage to the plastic tips of US 36 and US 50 sizes.
