styrofoam covered with fabric wall art. My daughter and I did this for her room. We used cheap painter canvas and scrapbook paper. We sprayed adhesive glue to the canvas and layed the scrapbook paper on top.
How great is this use of that small attic space.a personal, private closet space. I really like the reflective ceiling with the use of lights and white paint to provide a light space. I'm picturing an art studio rather than closet.
