My first question is why the quilt is laid on the bed the way it is. To me it is sideways. Shouldn't "Dallas" be at the foot of the bed? Would it then be wide enough and long enough as a bed topper - it may not have much overhang.
Another option is use it as a wall hanging or a throw quilt. Unless you just have your heart set on it being on the bed with an overhang, I would just use it as is. I have a lot of quilts that are I use as throw quilts or bed toppers.
