HOW TO: For our boards we used old picture frames that we purchased at a thrift store. We removed the glass and used the cardboard backing as our blank surface. We also painted the frames with acrylic paint and sealed them with Glossy Acrylic Spray. Casey covered her flat surface with scrapbook paper pieces while I chose the full-on collage route, covering every inch with things cut out of magazines and, of course, a little glitter on top.
P.S. Colored frames are a perfect way to brighten up and finish off any collage, no matter what the purpose.
