can/has it been done?? home made headliner...

Okay this is my biggest challenge my reconfiguration of the car. Everything else is just paint or bolt-on in sand or something like that but this is total fabrication. I researched some of my materials at Home Depot like maybe trying some ultra thin plywood And my idea was to make all four separate pieces and connect them together with some kind of hinging process. Now I know this will make a heavier crease at the control joint areas but I don't mind them or squared off look. As long as it looks good. Of course it'll be covered with the fabric of some kind so I'm sure a lot of imperfections can be hidden. I was at JoAnn Fabrics looking at the headliner material and then I turned and seen the fux beaver skin! What is wrong with my brain!?
