Using your addi Turbo Circular Needles is easy. First, choose the right needle size for your project. Slide your yarn onto the needle, and start knitting as you normally would. The nickel coating helps the yarn move smoothly, so you can work faster. When you're done with your project, gently remove the finished piece from the needles. To clean the needles, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials as they may damage the nickel coating. Store your needles in a safe place to prevent bending or breaking. Remember, some of the smaller sizes have non - standard US sizing, so double - check the size before starting your project. And the US 36 and US 50 tips are plastic, so handle them with a bit of care to keep them in good shape.
