Back to the drawing board!!! I got the foam on the headliner, that went well. When I laid my chosen material on the liner to see how it would look and check the fit as there are some compound curves, I discovered that it wasn't going to work. There is not enough give in the material to stretch over some of the curves, I would have had some wrinkles. So now I am going to have to go with regular material but I'm still going to do something different.. Oh well, a lesson learned!
