Using addi Turbo Circular Needles is easy. Simply thread your yarn onto the needle and start knitting as you normally would. The nickel coating helps the yarn move smoothly, so you can work faster. When using, be aware of the non - standard sizing of some smaller needles. Make sure to check the actual size if you need precise measurements. For maintenance, keep the needles clean. You can gently wipe them with a soft cloth after use. Avoid using abrasive materials that could scratch the nickel coating. Store the needles in a dry place to prevent rust or damage to the plastic tips (for US 36 and US 50).
