Go to the goodwill or thrift store. Buy the cheapest old picture frame that is a little bigger than the size that you need. Then go to any Aaron Brothers or any place that frames picture and they can cut it to size for you. (usually for free if you ask nicely) Then sand down the edges so it's not so sharp.
Cheap. Easy. DYI sorta...
