So the story goes that our roommate (who does not live with us anymore) slipped in the bathroom and somehow managed to break the cabinet door off the wall part of the cabinet. The point is when she pulled the door the bottom hinge tore out and caused a hole (approximately 3"x3.5") in the particle board wall of the cabinet. I don't know if there are any fillers I can use to patch this up that will hold the hinge and door. I'm fairly handy and have just recently started with simple wood working projects so please forgive my lack of terminology. I really do not want to replace this whole cabinet wall structure if I can avoid it. Any suggestions or help would be greatly appreciated!
