Did you ever pass notes when you were in school? When I was in middle school, my friends and I used to write notes to each other all of the time...we even had special ways to fold our paper.
My friends gifted me this sweet postcard they picked up at a farmer's market last weekend. The cutest element of the post card is its pastel green envelope on the front. When you open it up, there is a tiny little piece of notepaper to jot down all of the little secrets you want to hide from the postman!
