I just do a regular binding, and do the corners the same as a quilt, but angle the fabric so it lines up the same amount as the angle of the table runner. In other words, on a quilt you would make a right angle( 90 degrees ) at the corners. On the table runner it might be 45 degrees. Is that clear? Hope it helps. I always start and stop on one of the long sides too, so it's easier to finish the binding.
