Using these addi Turbo Circular Needles is a breeze. Start by choosing the right size for your project. Slide your yarn onto the needle and begin knitting as you normally would. The nickel - coated surface will help the yarn move smoothly. When using the smaller needle sizes, keep in mind the non - standard sizing mentioned. Be gentle with the cords to avoid tangles. After use, store the needles in a dry place. You can wipe them with a soft cloth if they get dirty. And don't forget, the US 36 and US 50 plastic tips are delicate, so handle them with care.
