Batting will make it very heavy. I made two quilts the same except on one I used batting and one not. The one with batting is heavy and the parents put it on the floor. The baby literally falls on it. Using it on a bed would not really work.
I have also brought the minkey over from the back to bind it. It works, but be careful of the corners. Minkey is "thick" and some corners work better than others.
Good luck!
