Using addi Turbo Circular Needles is a breeze. Just start your knitting project as you normally would, and enjoy how the nickel - coated surface allows the yarn to slide easily. When working, be aware of the non - standard sizing for some of the smaller needles, so you get the right gauge for your project. After use, gently clean the needles with a soft, dry cloth to keep them in good condition. Store them in a safe place, away from sharp objects that could scratch the coating. If you're using the US 36 or US 50 plastic tips, handle them with care to avoid breakage.
