Using addi Turbo Circular Needles is easy. First, choose the right size needle for your yarn and project. Slide the yarn onto the needle and start knitting as you normally would. The nickel coating helps the yarn glide smoothly, so you can work faster. When using the needles, be aware of the non - standard sizing for some smaller needles. Also, since the US 36 and US 50 tips are plastic, handle them gently to avoid breakage. To maintain your needles, keep them clean by wiping them with a soft cloth after use. Store them in a dry place to prevent the nickel coating from corroding. With proper care, these needles will serve you well for many knitting projects.
