If you're using a OEM-style headliner fabric its probably going to be super porous. There is a sweet spot of how much adhesive to spray and how long to let it tack up. If you skimp on it you'll end up with sagging spots, if you over do it you'll push the glue through the fabric and it will look like shit. I'd take some extra fabric and practice applying it to a piece of cardboard to see how long the particular glue you're using needs to tack up. I always use Super 77 Spray Adhesive but I'm typically using a thicker fabric, so YMMV.
Getting the corners and dips and curves right takes a while. Start it on a Saturday morning so you have plenty of time, I made the mistake of starting mine on a Sunday afternoon and I was still in the garage at midnight. Just be patient and have plenty of extra material. A fresh box of rubber gloves that you can burn through is a good idea, that way you can quickly switch from sticky hands from the glue to clean hands for laying down the fabric.
