just started..what can I do for a quick fix???

its falling in a small space on the driver and passenger recessed area..

 

Try sticking some pins in it to hold it up and keep it from pulling away further.

 

Its like the song " raindrops are falling". Once the headliner starts falling it keeps falling no quick fix is going to stop it. SORRY.

 

just recover it. They sell a kit at pep boys for like 50-60 that comes with the material and a can of adhesive, I recovered mine on my first car at 16 with no experience and it came out great, its not hard and cheap.
