Headliner question

I helped a friend install a Legendary headliner in his '66 Coronet. There was a little trimming to do where the bows insert into their sleeves. Other than that, we used spray adhesive on a few places and lots of little clamps to keep it where we wanted it until satisfied with the fit. I don't have pics, but it turned out perfectly, and neither one of us had any previous experience installing a headliner. If you do it yourself, set up a table on saw horses or something and let the headliner relax in the sun. It will be a lot nicer finish. Once you get it all clamped in place, then work out any wrinkles.
