Diy Interior.

Hey guys I'm trying to do a little planning ahead on my interior. I have been doing alot of thinking about my headliner. I have the foam backed hard (cardboard) style liner I have been looking online and in catalogs cant seem to find any all the ones I see is the soft cloth type with the bows. I have been thinking about just trying to do one myself and make one. I can get cardboard for free at work so I'm thinking get some cardboard and cut and piece it to fit then glue or epoxy all the seems to make it look clean and not pierced together then use some type of cloth or vinyl and spray adhesive and glue the material to the cardboard then use some clips around the edges under the trim to keep it together and tight. Has anyone ever tried or done anything like this before? Here are some pics of my current headliner. Unfortunately everything needs replaced. Headliner sail panels sun visors seats dash pad I'm not sure about the door panels yet I'm gonna try and save them
