Does anyone have any tips on reinstalling my old pop-up material? I rebuilt my whole camper from the frame up and I’m finally to the stage of reinstalling my cleaned up pop up material. It was in really good shape and had new windows sewn into it so I wanted to reuse it. It seems like it’s too small now I start attaching it from the back working my way up the side around to the curved front corner and I can’t get it to go back on it’s like it shrunk? I noticed it was stapled on originally and I pulled all the thousands of staples and cleaned everything up. Does anyone have any tips on the process should I start at the back corner?
