Addi Interchangeable Needles are great for so many reasons. We love how you don’t have to knit onto new needles when a pattern calls for one size of needles for Cast On, and another for afterwards. Simply click the new size on your cords and you’re good to go! Julie really loves these because she purls with a smaller needle than she knits to regulate her tension, and you can only do this with an interchangeable set. These needles never come loose, or unscrewed. They stay right where you need them so you never lose a stitch!
