They do have wider fabric for backing (102", 104", 108", 110", etc.). I will try and buy that if I'm making a gift where I want a solid backing and no design. I've seen seams down the middle, two seams each off center, seams running across the quilt sideways in the middle and also off center. I guess it depends on the fabric you select and if you are going to have a solid backing or add some design to it.
