After dinner, Uncle Marvin kept his word by showing Tina how to learn more about letterboxing on her computer.

He showed her where to get clues, and where to learn to read a compass.

They even found a cool area just for kids that showed how to make a special tool for carving rubber stamps. It also showed how to make stamps by cutting up foam pads with a pair of scissors.

Tina would go letterboxing with Uncle Marvin again soon. Next time, Tina would even get to hide a letterbox of her very own for someone else to try and find.

Letterboxing is fun!
