I was inspired by Einat Kessler 's beautiful Pop Up Book using Graphic 45 Paper. You can see her book here along with a tutorial to show you how she made hers-
Elinat's is gorgeous! Mine is a poor attempt to imitate a Master! But I didn't make a book! I was content to try my hand at a card!
Here are a few more pictures. I found it hard to get good pictures so I did a quick video that you see above. I thought it was easier to show you how it opened.
