Hang a curtain rod draped with sheer curtains (or fabric) at headboard height, behind the bed, then add some white holiday lights behind the fabric and across the rod.--- maybe just a string of lights over the headboard :)
Make your own fireplace.no chimney required. Use an old mantle structure and have several candles serve as your "fire." This lovely vintage room lends itself perfectly for this idea well. White mantle and mirror, candles and lanterns.
