Using addi Turbo Circular Needles is easy. First, choose the right size needle for your yarn and project. Thread the yarn onto the needle and start knitting as you normally would. The smooth nickel coating helps the yarn move freely, so you can work quickly. When using, be aware of the non - standard sizing for some smaller needles as described. After you're done with your knitting, gently clean the needles with a soft cloth to keep them in good condition. Avoid using harsh chemicals or abrasive materials as they can damage the nickel coating. Store the needles in a dry place to prevent rusting. And don't forget, the US 36 and US 50 tips are plastic, so handle them with care to avoid breakage.
