You could try different things. A single piece of plywood would be one but two pieces will control the reaction to "drawing" better by keeping edge ruffles from forming. You could screw through the...

Jon,
I think flanges could work. There may be associated problems, but I'm not sure what they would be. Flanges would take away your ability to shrink edges, but they would help keep the edges flat...
