The page that shows all of the gifts has the same picture of the room for the last three steps.  At first, I thought that's what you got for the theme, just a bigger version with each step!  LOL  Good thing I visited someone's loft and they had saved on the dark Vampire Diaries room.  Now I'm tempted to do it, at least through the second-to-last step.

The last thing I need right now is more stuff (the downside of all of these quests), but I do like the idea of different themes for the same room.
