Using these addi Turbo Circular Needles is easy. First, thread your yarn onto the needle and start knitting as you normally would. The nickel coating helps the yarn move smoothly, so just enjoy the process and let the needle do the work. When it comes to sizing, double - check the actual size according to the non - standard sizing note we mentioned. As for maintenance, keep these needles away from sharp objects to avoid scratching the nickel coating. You can gently wipe them with a dry cloth after use. If the cords get dirty, a mild soap and water can be used to clean them, but make sure to dry them thoroughly before storing. These needles are designed for long - term use, so take good care of them and they'll serve you well for many knitting projects to come.
