Using your addi Turbo Circular Needles is easy. Just thread your yarn onto the needle and start knitting as you normally would. The nickel coating helps the yarn glide smoothly, so you can work quickly and efficiently. When using the needles, be aware of the non - standard sizing of some smaller needle sizes. Always double - check the actual size. For maintenance, keep the needles clean by wiping them gently with a soft cloth after each use. Avoid dropping or bending the needles, especially the plastic tips on the US 36 and US 50 sizes, as this could damage them. Store the needles in a dry place to prevent rusting on the metal parts and to keep the plastic tips in good condition.
