Yeah, knowutcha mean. If I'm photographing a finished built-up, especially if it's for an article, album, auction or some such, I usually try to use a "presentable" backdrop.
Otherwise, almost anything will do. If I take some shots of a piece in-progress, I like to use my workspace as a backdrop. It's kind of fitting, I think.
I do draw the line at frilly curtains, though!
