Here is a lofty idea... se what I did there, XD

That's so cute! What did you use for the loft flooring? I made mine with the zabuton cushions, I've heard about the box shelves, but that looks like one of the stages? I wasn't aware those could be floated!

It's a very hard to accomplish glitch, it involves placing items from storage in your house. It was much easier before they patched the UI glitch in 4.2. Basically you have to "place" the stage on the top of a window, door, or railing. You need to be in first person. I'll try to find a link to the post and edit this with that unless someone else posts it before I find it.
edit: I see Elamys beat me to it! :-D
