Using your addi Turbo Circular Needles is easy. Just thread your yarn through the cord and start knitting as you normally would. The smooth nickel coating will help the yarn slide easily, so you can work quickly. When it comes to care, keep the needles clean and dry. Avoid using them with abrasive materials as it could damage the coating. Also, be aware of the non - standard sizing for some of the smaller needles. If you're using the US 36 or US 50 needle tips, remember they're plastic, so handle them gently to prevent breakage.
