I made this box to hold 3" note cards. I used the each image from the Pun Fun set for the note cards. I also made use of my new Jumbo Marvy square scallop punch, both on the front of the box and on the cards inside.
The outside dimensions on the box are 3-1/2 by 3-1/2 by 1. Start with 6-1/2 by 10. Score lines are at 1/2, 1-1/2, 5 and 6 inches on the narrow side. The wide side is scored at 2-1/4, 3-1/4, 6-3/4 and 7-3/4 inches.
