Using your addi Turbo Circular Needles is easy. Start by threading your yarn through the needle tip. The smooth nickel coating helps the yarn move along without any hitches. As you knit, enjoy the flexibility of the cords, which allow you to work on large projects comfortably. When it comes to sizing, double - check the actual size as some smaller sizes don't follow the standard US system. After use, simply wipe the needles with a dry cloth to keep them clean. Avoid using abrasive materials on the nickel coating. Store your needles in a dry place to prevent any damage to the plastic tips on the US 36 and US 50 sizes.
