Using addi Turbo Circular Needles is easy. First, choose the right needle size for your yarn and project. Slide the yarn onto the needle and start knitting as you normally would. The nickel coating helps the yarn glide smoothly, so you can work faster. When you're done, be careful not to bend the pliable cords too much. For cleaning, you can gently wipe the needles with a soft cloth. 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, avoid exposing them to high heat to prevent damage.
