I'm going to do a frame collage like this for the living room. Not sure yet if I want the frames to be all the same color or not. Some will have pictures in them and some will have personally crafted pictures/collages.
The room as a whole is too flea market for me, but I love that the room is colorful. I would not have color on everything, but one or two pieces is nice. I love the green doors on the wall as art - their color, texture and style appeal to me.
