Jeff and I have a lot of stuff. Our apartment has been described as "like a museum," although I'm not sure what kind - a museum of trash American culture, perhaps? In any case, when we moved in I started to see themes in our gew gaws (monsters, toys, religious) and decided to display things around the house in little dioramas, or tableaux, or whatever you call thematic or dramatic groupings of things. Here's one - it's sort of a dangerous tropical nightclub scene, with the Creature from the Black Lagoon, day of the dead figurines, sixties dollhouse furniture, and a black velvet painting.
I find this kind of thing very creatively satisfying. It's simultaneously home decorating, playing with a dollhouse, collecting, organizing, and displaying.
