This wall over the sofa currently has three similarly-sized pictures that aren't big enough for the wall. Now I have two more medium sized ones, one tiny one and a long skinny one that I am going to try to arrange so they look a little less like I attempted to have everything match and failed. We will see if I have any luck. I will possibly even scrounge a newspaper somewhere so I can cut paper templates and make sure everything is spaced out evenly.
Also no, the living room has not changed much since we moved in. You can compare and contrast once I get this danged art hung up. And photographed with my snazzy new lens!
