thanks for sharing your backdrop method along with your elegant photos! this is the sort of great idea that's so simple, I know I'm in good company slapping my forehead and saying "why didn't I think of that? a long time ago??" LOL
when I even think of the background, I grab something handy -- like a towel or a t-shirt. that does hide clutter, but it doesn't elevate photos to the level of art.
