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.
Display bits of fabric that you like instead of keeping it in a box. Fabric is art in itself. You can find embroidery hoops all the time at garage sales and thrift shops! Maybe even paint the hoops to give a little color to the fabric hoop wall!
