Using your addi Turbo Circular Needles is a breeze. First, thread your yarn through the cord and onto the needle tip. Start knitting as you normally would, and enjoy how the nickel - coated needles let the yarn glide easily. When you're done with your project, gently remove the yarn from the needles. To keep your needles in top condition, avoid using them with rough or abrasive yarns that could scratch the coating. Store them in a dry place, and if they get dirty, you can wipe them down with a soft, dry cloth. Just remember those special sizing differences and the plastic tips for US 36 and US 50 needles.
