A fun small project that can be finished in about an hour. I found the pattern at freeprintable.com. They have several other gift box patterns.
I needed a glass board for cutting on, a small razor knife (scissors would work as well), a steel ruler, a large pair of straight hemostats (optional) and a tube of super glue. You want to use heavy cardstock as opposed to regular printer paper.
The pattern from freeprintable.com is where i started. But I wanted to change the exterior decoration. You can find hundreds of websites to get something you like. I picked a colorful exterior and then a black and white floral for the interior. You establish the interior by printing on the reverse side of the sheet.
