I wanted my loft hatch to look like a skylight so I took these and wrapped them around the hatch door. There are still some creases visible when looking at it from below (I tried rolling it up for a few days as suggested to get the creases out but it didn't help much) but overall it turned out very well. It was very easy for me to wrap it around the hatch door and cut off the excess I don't need. I think it will hold up well because it's a bit thick, but not enough to prevent the sunroof from sliding around the opening's frame. I'm happy with it and have some left over for another project if I have one.
