Headliner installation "can i do it myself?"

I installed one in a 69 Dart many years ago, it went pretty well except for the rear panels where it comes down the sides. It was wrinkled, and since then I have learned that a hair dryer helps to get them out. It was also tricky getting it glued under the rubber around the front and rear windows, take it slowly and keep all the roof bows in order front to back. Not much help but my 2 cents. Good luck!
