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

I used a flap sander to massage a couple long edges just to tighten things up. I'm sure this would have came together easier if my template wasn't CRAP ! but I would have had a much harder time with it had the car not been gutted.
I was able to tuck the back in the rear seal, but since I don't have the front windshield or seal I was starting to have a ruff go. I did leave it with a good fealing. I want to give it more tape (reinforcement).
A couple things at this point - $14 for 4×8 wood and $6 for tape. Also I used the metal cutting blade that was already on the jigsaw as it seemed to work very well on the thin wood.
If this next test fit goes good I'll attach the 4 piece with something better than tape and glue on a headliner material. Witch also should further reinforce?
