I usually leave enough batting along the edge to fit "under" the binding. In other words, I cut the edges of the quilt leaving about 3/4" of batting around the edges....then sew the binding...2 1/2" folded in half, to the back. Then, when I fold the binding to the front, none is left to show on the back, I have an easy 1/4" or a bit more, to fold over the quilt edge and then I sew a decorative or straight stitch. Sometimes I stitch two rows of straight stitches if it's a kid's quilt that will be washed a lot. I hope I made that clear. It's such a great finish that I use it most of the time.
