Using your addi Turbo Circular Needles is easy. First, choose the right yarn for your project. Since the needles are nickel - coated, the yarn will glide on them effortlessly. Just start knitting as you normally would, and enjoy the smooth process. When it comes to the smaller needle sizes, be aware of the non - standard US sizing as mentioned. This will ensure your project turns out the right size. After use, gently wipe the needles with a soft cloth to keep them clean. Store them in a dry place away from sharp objects to avoid scratching the nickel coating. And don't worry about the plastic tips on the US 36 and US 50 needles; they're durable but just handle them with a bit of care.
