We found this over at CXWWW's flickr page: Hotel de Banville's alternative headboard. Mounting a curtain rod to the wall and extending it the length of a bed, the tab-top padded "headboard" slides on. Advantages? Easy to change out and even easier to clean. Disadvantage? Probably not as stable as the real thing. What do you think?
