I recently sewed a temporary headliner for my '62, just to see if I could do it. I've made some seat upholstery before but had never made a headliner. I used a piece of cheap canvas, but will use the correct vinyl when I make the real one. I've seen a good video on Youtube showing how its done, but it is in Dutch or German but after watching it a couple of times its not too hard to figure out. Take a small scrap of vinyl, fold it, and poke the ends of the bows thru it to keep them from rotating. At the moment I can't remember the title of the video, but I have it written down some where, & will post it later.
