You can find instructions for the ornament here. The paper version is something I made up to make it easier to understand how the ornament goes together, but it would also make a good favor box I think. To make it, print out the template on paper or card stock, and glue the blank tab inside the other side of the box. Then tape down the tabs to close it. I lined up the lines so that it will all line up right if you tape them on the outside. I used paper for the version above and didn't score or fold the lines.

The blank version is for you to decorate, I think it would be great filled with candy as a place card!
