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.
Fun art project with the kids! Easy abstract painting that anyone can do! Just blob the paint on the canvas in random spots and blend! (would be interesting how students could make different pictures w/ the same colors and same blob positions)
Paper boxes used for the walls as art. Affordable wall art, unique wall display, ways to decorate your home. You can also use art canvas and cut out a pattern from behind it with a repetitive stenciled pattern
