We usually take a very light-handed approach when it comes to artwork in the bedroom. Since our walls are the first thing we see in the morning and the last thing we see at night, as well as what we might stare at hoping for rest during the occasional insomniac episode, bedroom art and arrangement must be carefully chosen.
One way to make sure artwork doesn't overwhelm, no matter the piece, is to display it a bit more casually than you would in another room. The bedrooms above display groupings of framed and sculptural artwork leaned casually against a wall on the floor.
Another approach is artwork as headboard. The benefit here is that the display accessorizes the bed, but isn't in front of your face while you're trying to sleep — so it can be a little more active and edgier.
Finally, shelving behind the bed combines aspects of both the casual and headboard artwork displays: art can lean on the shelves behind your head. This is especially good for small bedrooms that can't accommodate side tables, as a clock radio, book, carafe, and other bedside needs can be interspersed among the artwork.
