I have transitioned from 2.5 to 2.25 and now I do 2 inches. It is a thin binding but it is full and even. I don't use a walking foot and I don't serge the edge. I've been happy with the results. I like to sew in front and hand stitch to back. I don't have any arthritis, carpal tunnel issues, etc that keep me from doing this. If I am going to sew on the back and machine stitch to the front I do a 2.25 binding.
