I always make my own bias binding. I cut 2 1/2", seam on the diagonal, fold in half, press, sew to the front and hand stitch to the back. I sew to the front using my walking foot and am very careful not to pull on it while stitching just let my machine feed it. It's funny, but to me I think the bias binding is very forgiving when I am hand stitching. I have never had a pucker.
