Recommended Interchangeable Needles: Twist 5-Inch Red Lace by ChiaoGoo
My favorite interchangeable set of needles I’ve used is the ChiaoGoo Red Lace set. I’ve had these since I was in high school, and they are always the first set I grab when casting on. You can use a key to screw the needle into the cord, and I very rarely have issues with the joins coming loose. In addition, they have extension sets for shorter tips to use for hats and other small projects.
