I used to have difficulty with bindings until I took a class at the LQS that taught us to use a tool put out by Missouri Quilt Co. We were told that there is a smaller tool to use like on potholders. I do find that I like to use a 2 1/2" strip folded in half. I stitch to the front and use a 3/8" seam allowance then fold to the back and hand stitch. One could machine stitch, as well, using a decorative stitch. The tool helps to eliminate the bulk when finishing. Good luck!
