This is the link where you will find a very good tutorial on how to make these little books. You use 3 #10 size business envelopes, solid CS, and some designer paper. You also need several punches. This was fast and easy and I plan on doing more as I really enjoyed this project. I used the new Main Blueberry DS from Stampin' Up!. Love this paper! It goes with Not Quite Navy and Old Olive colors. Enjoy!
