I'm debating on taking on the task of creating a one piece fiberglass or material covered fiberboard headliner. I wouldn't mind going with the normal headliner look but every time I call a upholstery shop for a price they all charge $500 and up. That's with me supplying the headliner and window gaskets. For that price I'm sure I could have something done like a fiberglass one made. Why do they charge so much? While I was searching the threads here I came across people who said they only paid $100 or so. Is the cost of living here in the California bay area that expensive?
