Wall arrangements are the easiest way I become bored these days. Nail holes? I'm really not worried about them. They're easily covered up by new art arrangements, and by the time I leave my apartment, I'll slap a coat of drywall compound over them and sand away.
Right now I'm torn between finding some classic neutral colored art that will let my funky floral sofas and pillows shine, or even taping up lots of colorful, unframed postcards and magazine clippings. The wheels in my head are spinning!
