I made a wine bottle cake once. It was a very short notice so I did everything on the fly. I had a wine bottle that I laid out and placed corn starch over and then fondant. I used the big tomato soup cans and baked some cake in those and placed that behind the fondant once it was hard enough. I had to use a real paper for the wrapper because it was a last minute thing. It all worked really well.
