The windows along my studio apartment's back wall extend the full width of the apartment (about 20 feet). But there's this awkward blank wall space between the bottom of the windows and the floor that I'd love to do something interesting with. As you can see in the photo, I do have a through-the-wall AC unit in the middle, plus really ugly baseboard heaters along the floor.
Any ideas on what to do? I'm totally open to paint, wallpaper, art, etc. Help me brainstorm!!
