Using these Addi Turbo circular needles is easy. Just thread your yarn through the cord and start knitting as you normally would. The smooth nickel coating helps the yarn move freely, so you can work quickly. When it comes to the smaller needle sizes, double - check the actual size against the label as they don't follow standard US sizing. To keep your needles in good shape, avoid bending the cords too much and store them in a dry place. If the needles get dirty, you can gently wipe them with a soft cloth. The plastic tips on the US 36 and US 50 needles are delicate, so handle them with care to prevent cracking or chipping.
