I made these mini Explosion Boxes as a little thank you gift for those guests who came to my stamp club workshop. I put a Hershey's kiss inside.
To make the mini boxes use a 3-3/4" x 3-3/4" square and score 1-1/4" in from each side.
To make the lids use 2-3/8" x 2-3/8" square and score 1/2" in from each side.
