So, I have this old Persons seat, I want to cover it. But, there's no pan to attach the leather to. I trying to think of things I could build one out of...fiberglass? Would definitely work, but, can I staple to it?? I don't think so (not 100% sure on that though). So, I thought, "what about paper mache?" It's easy, way cheaper than glass, and, from what I read, it can be as strong and as easy to work with as wood. Has anybody attempted this? And, to what results?
