So I plan on redoing my headliner. I am curious if anybody knows how much fabric I would need? I am custom doing it black and laying a British flag on top of it. I would just measure it but currently at work and don't have time today to measure it. I was planning to spray and lay a black headliner fabric with a foam backing and then gluing a polyester flag on top of that. I am choosing black, in case the glue cause it to bleed through a little.

 

See if this DIY may help, it has some good info about how much fabric used, etc.
