I was very much inspired by insect display cases, so I created a story around that. Being trapped behind the glass. Yet now, finally able to break through. It represents a dividing point between two phases in your life.
This turned out to be more complicated than I intended! The butterflies all needed to have their wings broken then glued back on because their wings were up, not out. Also breaking a hole in the center of a glass sheet is really difficult lol, so we had to hand crack the center little by little.
