Letterboxes allow us to fit some creativity in too! It is a hidden treasure (hand-carved stamp and log) you bring a stamp pad, your hand carved stamp and a log of your own! You stamp in the log and "collect" their stamp in yours!
I love the idea of a world of trails with little art treasures waiting to be found! Pic from my log I left (I am rocking the monkey stamp), Woo hoo- how are you spreading the creative love in your world?
