Scrapguy ~I found his Tutorial for the Exploding box very easy and made this..
You will need 4 sheets of Paper to do this project.
The first sheet is cut 9x9 and scored 3" on each side
The second sheet is cut 8 and 5/8 x 8 and 5/8 and scored at 2 and 7/8 on each side.
The last layer is 8 and 1/4 by 8 and 1/4 and scored by 2 and 3/4 on each side.
and then last is the lid~it is 6 and 1/4x 6 and 1/4 and scored by 1 and 1/2 on each side.
You will cut the corners around each side except the lid~you may want to go to his video so you can see how that is done.http://scrapguy.blogspot.com/2010/07/paper-crafting-exploding-box-with-video.html
