I made a similar card to this at a workshop a couple of months ago. My friend insisted that since I had all the stamps I needed to make another one of them. I got crazy and decided to go for it even though it is a feat of engineering. Here is the closed front looking like your every day gatefold card with a spot of twine holding it closed.
