When my siblings and I were little, my mom would take us shopping as soon as school let out for the summer. We would spend an afternoon stocking up on toys and crafts to keep us busy during the summer break. It was a kid’s dream.
One of the craft projects Mom would suggest involved writing a secret message in white crayon on white paper, then painting over it with watercolors to reveal what we wrote.
We thought exposing the hidden message was so neat, and frankly, I still love the idea of hidden messages.
