Using addi Turbo Circular Needles is easy. Start by threading your yarn through the cord and onto the needle tip. Then, begin your knitting stitches as usual. The smooth nickel coating helps the yarn move freely, so you can work faster. When using these needles, keep in mind the non - standard sizing for some smaller needle sizes. This way, you'll get the right gauge for your project. For maintenance, simply wipe the needles with a dry cloth after each use to keep them clean. Avoid using harsh chemicals as they might damage the nickel coating. If the cords get tangled, gently untangle them by hand. Store your needles in a safe place, like a knitting case, to prevent them from getting bent or damaged.
