I just learned to do bias binding and one of the seams ended right at a mitered corner. It was a mess trying to get the corner to lay flat. I machine sew the binding and the sewing machine wasn't happy about going over all of those layers plus it created ugly stitching on the back. That said, the bias binding was a breeze to put on since it was a tree skirt and was hexigon shaped with an inside circle. I just did not like all of the joined seams.
