Using your addi Turbo Circular Needles is easy. Start by choosing the right needle size for your project. Thread your yarn through the cord and onto the needle tip. Begin knitting as you normally would, and enjoy how smoothly the yarn moves. When you're done with your project, gently remove the yarn from the needles. To maintain your needles, keep them in a dry place. Avoid bending the cords too sharply, as this could damage them. If the needles get dirty, you can wipe them with a soft, dry cloth. Remember, the smaller needle sizes may not follow standard US sizing, so double - check before starting your project. Also, be careful with the plastic needle tips of US 36 and US 50, as they can break if mishandled.
