I am redoing the headliner in a camper.
The ceiling corners are curved both vertically & horizontally. Original has vertical trim molding which ends 2" below the curve. So it is a square piece of foam backed vinyl with 1 corner curved & a V shaped slice in that corner. I am getting wrinkles in this area.
The foam backed vinyl has stretch in only 1 direction. It is glued on. I do have more vinyl to redo the corners.

Any advice on how to do this with no wrinkles?
I will post a picture on Monday (out of town now)
Thanks

With respect to a headliner regardless of it being and RV you need to keep the material and substrate separated, then use 1 hand to put the fabric under tension and then make contact with the substrate.
