I have never done this, but I would think you could make a faux top out of fondant and gumpaste and just lay it against the back. Decorate the "inside" of the cake to look like tissue paper hanging out using fondant.
Have you searched the picture gallery? There has to be a picture of one that some amazing cake artist made!!!!
Good Luck!
