I am really happy with the way this box turned out since I have never made one before. I'm sure it will be even easier the next time around. I found the directions for this here. I used my favorite set, A Good Egg, and filled the box with "bunny corn". I'm off to spend the morning at school with Cameron for his 100th day celebration.
*EDITED*- I had a few people ask where you can purchase acetate. I actually bought a package of overhead transparencies at Staples. They are 8 1/2 x 11 sheets, and that is what I used for this project.
