Expandable Card Box

I thought this was a cute idea to holder your cards that you have made or handmade cards you received from friends.

This is the inside.

I found instructions from this website http://paperboutique.blogspot.com/2010/04/expandable-card-box.html There are easy instructions to follow and a video to watch how to make it if you run into trouble.
