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

Okay the 73 duster card board headliner Boogeyman has been broken. The biggest problem was my template . And also the way I cut things out. It should have been a lot more matching as if they were cut out of one piece. But my material size was 5 foot by four and a half foot so this would not fit on a 4 by 8 sheet all in one piece. Know if someone took the same piece of wood and was able to have like a 5 by 5 foot piece of wood I'm sure if they wanted to get real precise they can make inside relief cuts (with a router) also put hinges on the backside of it and it would come out extremely slick . But as it is the separate pieces it's better in separate pieces for how rigid the wood material is. If my actual glue on reveal material was like a thin vinyl (to reproduce the original cardboards textured vinyl look) or even that modern stuff (1/8 inch foam with material) I'd go spend another 14 bucks and just get another 4x8 sheet and just take more time, but again I believe my material choice should be very forgiving. One could just rattle can some black wrinkle paint or even do some Plasti Dip and be able to change the color? And probably not be into this more than $40. I'm not getting a hokey cheesy feeling, but I'm NOT driving down the road three years later telling people how easy it was. THIS STILL NEEDS TESTING
