Using your addi Turbo Circular Needles is easy. Just thread your yarn through the needle and start knitting as you normally would. The smooth nickel coating helps the yarn glide, so you can work quickly and efficiently. When you're done with your project, gently remove the yarn from the needles. To clean the needles, simply wipe them with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials as they could damage the coating. Remember, some of the smaller needle sizes don't follow standard US sizing, so double - check the actual size before starting your project. Also, since the US 36 and US 50 needle tips are plastic, handle them with care to prevent breakage.
