Below is an image from The Hours of Catherine of Cleves. A book of hours illuminated in 1440 in the Netherlands. It is what started this project!
And here is the version that I made. For all of the documentation on this click (Here.pdf)

In the Documentation there are references to different samples of boxes that I folded comparing the resulting sizes. Here are some images to help you out.

These two boxes were made with 8"square pieces of paper but different techniques.
B was made with a 10 1/2" square piece of paper, F with 11" using an oragami technique.
