I do trim the corner of the layered quilt slightly to give myself a little extra slack in the corner. It reduces the bulk, especially where your binding will be folded when you miter the corner.Once you have your binding folded to the back, extend the binding past the side of your quilt in the corner. Make sure that the perpendicular binding is extended to the fullest on its side.
Then finger press the binding down making a 45º angle. Then fold the perpendicular side down on top of the first side to complete the corner. Most of the time, I pin the first side so it is secure and doesn't move as I fold the second side down.
You now have mitered corners on both sides of your quilt binding.
Happy Quilting!
