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.
Vertical Succulent Planter in bathroom. For a bare wall, such a planter becomes much like a living piece of art. Easy to grow plants include dudleyas and sedums. They grow very easily from cuttings. Once established, these plants require little water.
