Headliner

Hey, I wanna redo the headliner of my friends 82 monte carlo in white vynol. He's getting the seats wrapped in white, so I thought thta'd be a good way to go. Anyways, I'm still not exactly familiar with how I'd go about getting the material on the headliner. The old liner is all sagging..it's litterally being held in place with thumbtacks. So removing that one is noo problem. Should I go with some kind of glue? Also. I wanted to place a grid of buttons on it, you know like on those old leather couches you have almost a little crater in which a button is sewn in. How should I go about doing all this? Get some foam maybe? then figure out a way to get that button look goin. I dunno, I'm lost. SOS!

The buttons are gonna look something like this...

Its the very last 2 pics. They have the buttons. I want it to look somethinglike that.

take the headliner down, like the cardboard backing and the cloth covering it, take off the old cloth.  get some 1/2" or 1" foam padding and glue it to the cardboard backing.  once you have done that wrap the headliner in whatever you want.  they make these buttons that have a small loop on the back side, find some of those and get a big needle and thread.  loop the thread through the back of the button and stick it through the freshly wrapped headliner where ever you want, and just tie it off on the back of the headliner.  do that until your done and just reinstall your newly buttoned headliner, hope this helps

Won't they go right through and poke out the other side?
