Using addi Turbo Circular Needles is easy. First, pick up your yarn and start knitting as you normally would. The nickel coating helps the yarn move smoothly, so you can work faster. When using, be aware that some of the smaller needle sizes don't follow standard US sizing, so double - check the actual size. For maintenance, keep the needles clean and dry. You can use a soft cloth to wipe them after each use. Avoid bending the cords too much to keep them flexible. Also, since the US 36 and US 50 needle tips are plastic, handle them gently to prevent scratches or breakage.
