My younger sister moved to Tucson over the Summer. I was really sad in the weeks leading up to her leaving, and I knew I was going to miss her like crazy. She's never lived away from home before, and now she was moving to a whole nother state! I mean come on, it was going to be difficult on her too. I wracked my brain for ways to make the move a little less painful, for both of us. After scouring Pinterest, I came across these "Open When..." letters. They are such a cute idea!...
