I used Super Glue (Gel, so it wouldn’t drip) and held the edge in place, over night, with simple black binder clips (from the stationary store). You can get clips in just the right size (not too big and not too small) to clamp around the curve of the lip of the pocket and to apply strong even pressure on the material all along the lip. You just have to be careful not to glue the clips to the material (apply sparingly only on the underside of the material). Also be careful not to tear the material with the clips. You can glue just a couple of spots, like tack welding. Then the next day, do a couple of more spots until you are satisfied with the smooth contour of the lip of the pocket. The Super Glue does harden the edge of the material, but it seems to be impervious to the heat. It stays hard even on very hot days with the windows rolled up. I think the heat is what caused my material to curl in the first place. I was told that the material is heat bonded to the plastic backing and it just pops free over time. Once before, I had an upholstery shop try to fix a sunroof cover and the upholstery glue would always get soft and gooey when the temperatures would rise. What a mess that was. No more upholstery shop glue for me. I use Super Glue. The Super Glue does not soften from the heat, so the material stays put, even though there is very little material to work with at the edge. The glue has been holding strong for four years, highly recommended. I think you can see that I do have a very slight bulge at the lip of the driver's side pocket, but it really looks very good. I am very particular about my car and I am happy with the fix.
