Using your addi Turbo Circular Needles is a breeze. First, choose the right size needle for your project, keeping in mind the sizing quirks we mentioned. Then, start threading your yarn through the needle, and let the smooth nickel coating do its magic to make the yarn glide easily. When knitting, the snag - free joins and pliable cords will ensure a seamless experience. As for maintenance, simply wipe the needles with a dry cloth after each use to keep them in good condition. Avoid using harsh chemicals or abrasive materials that could damage the nickel coating. And be careful with the plastic tips of the US 36 and US 50 needles, as they can break if handled roughly.
