Using these addi Turbo Circular Needles is a piece of cake. First, pick the right needle size for your yarn and project. Thread your yarn onto the needle and start knitting as you normally would. The nickel - coated surface helps the yarn glide smoothly, so you can work faster. When it comes to maintenance, keep them in a dry place to prevent the nickel coating from rusting. Also, be gentle with the snag - free joins and pliable cords to avoid any damage. Remember, some of the smaller needle sizes have non - standard US sizing, so double - check before starting your project. And don't forget that the US 36 and US 50 needle tips are plastic, so handle them with care to avoid cracking.
