Using your addi Turbo Circular Needles is a breeze. Just thread your yarn through the needle tip and start knitting as you normally would. The smooth nickel coating helps the yarn slide easily, so you can work faster. When it comes to care, simply wipe the needles with a soft, dry cloth after use to keep them clean. Avoid using harsh chemicals or abrasive materials, as they can damage the coating. Remember, some of the smaller needle sizes have non - standard US sizing, so double - check the actual size before starting your project. And don't worry about the plastic tips on the US 36 and US 50 needles; they're durable and add a fun sparkle to your knitting.
