Install headliner

If your headliner comes all folded up in box and you live where it`s cold, I`d make sure you lay it out for a few days in a warm place with weight on it. Those folds will take a long time to completely disappear if you don`t, no matter how tight you stretch it. Take lots of measurements beforehand so you can find your belt holes,coat hangers,etc and leave the listings as long as you can,only cutting enough off to get it in the bow hanger.Warm weather, a good quality glue, patience, and a friend with strong hands will help a lot. Let us know how it turns out. Good luck!
