If you are going to machine sew it on, I would recommend that you use a serger to finish your quilt sandwich and prepare it for the binding. This does a couple of things for you. First, it keeps all layers together nicely. Second, it feeds through the machine very nice without a walking foot. Thirdly, it gives you the 1/4 inch mark to make your mitered corners (YouTube tut will explain) without measuring. And lastly, in my opinion, it makes it easier to ensure that your binding is "stuffed."
