Range rover p38 roof lining

Any good ideas for repairing saggy roof lining? don't want to buy a new one

Do a search on it!
theres loads of threds on it,

My headlining was sagging badly and I picked up a perfectly good one from a Range Rover breakers for not too much. Not too hard to change over either. There are no real fixes except to replace it. I am going to recover the old headlining with new material eventually and see how that goes. I would just replace it to be honest.
