First time headliner install tips

I am going to install my headliner in my 66 barracuda this weekend. I would have messed it up royally had I not watched and looked at all the tips in here on it. both windows are out as I am doing entire car. I installed the headliner insulation tonight and tomorrow night I am going to hang headliner. I figure if I do a couple hours a day I wont get frustrated and quit. Hopefully Sunday I can post finished pics of beautiful new headliner.
