Using your addi Turbo Circular Needles is easy. Just thread your yarn through the cord and start knitting as you normally would. The nickel coating allows the yarn to move smoothly, so you can work on your projects faster. When it comes to smaller needle sizes, double - check the actual size as they might not follow the standard US sizing. Be gentle with the cords to keep them flexible. To clean the needles, use a soft cloth to wipe them down. Avoid using harsh chemicals as they could damage the nickel coating. Store your needles in a dry place to prevent rusting. If you have the US 36 and US 50 needle tips, handle them carefully as they are made of plastic and can break if dropped or bent.
