I couldn't find styrofoam the right size so I used 12x12 canvases (Michael's sells them in packs of 7) and mod podge. One layer of mod podge on the canvas, place the scrapbook paper and then let it dry. Then add a layer of mod podge onto the paper as a gloss. It might be wrinkly at first but the wrinkles go away after it dries :) @Amanda N
Good old Martha taught us that rather than buying those ridiculously expensive anti-slip mats for a rug, just turn it over and run a few lines of acrylic-latex caulk every 6 inches or so. Let dry and flip over and your rug wont be going anywhere!
