This is the scene I made from the original post of just one Halloween arch. I finished this last night and am really happy with how it turned out. I made "hinges" out of card stock and rotated them so the scene would open up accordion style. I am thinking about starting a swap for this type of scene.
I have some other arches in various themes that I didn't want to punch holes in and am thinking about doing this to those as well, so I can enjoy them by setting them out around the house.
