Using your addi Turbo Circular Needles is a piece of cake. Just thread your yarn through the cord and start knitting as you normally would. The nickel - coated surface helps the yarn move smoothly, so you can focus on creating your masterpiece. When it comes to the non - standard sizing, always double - check the actual size on the label. Be gentle with the plastic needle tips of the US 36 and US 50 needles to avoid breakage. To keep your needles in top shape, after each use, wipe them down with a soft, dry cloth. Store them in a cool, dry place, and you'll be ready for your next knitting adventure.
