Years ago the back of my grandmother’s quilts were bigger all around than the top so you could bring the backing fabric to the front to make the facing. I think her batting extended from her top, the width of what she wanted her facing to be and sewed down to the outer edge of her top, covering a seam alliance in top, of course.
I personally like the bindings they do now. We recently gave a veteran a quilt top I pieced, another member long arm quilted and because I had just broken my shoulder/arm another member did a facing like my grandmother used to make. I was a little disappointed, after putting so much work in it that I didn’t get to bind it my way but the guy was happy and the quilt was finished. Here is a corner of it with the darker navy fabric coming around to the front to make a facing.
