Beautiful, symmetrical pieces. They're all neat, but my favorite is the black one. Do you have any photos of the prizes (candy, small toys, etc.?) that you presumably packed into them?
These are all so beautiful! Question... did you build the structure from scratch? They are amazing!
@Patraw: I didn't fill these because my sister wanted the fun of filling them for her kiddos. Below is a pic of what I put in my doofy daughter's calendar. I had to ask her to give me the first 6 days because I hadn't taken a picture beforehand
@MissingWillow: Yup, from scratch. Most matchboxes form a rectangle on the side panels when stacked. I wanted the side panels to be perfectly square so I designed the cut files for the matchboxes and the top box in Adobe Illustrator. Used my Silhouette Cameo to cut them and slapped them together.
