I love postcards. I love sending them, I love getting them, I love buying them and then just keeping them on my cork board to remind me of the places I've been. Postcards are the best.
And now you can make your own!
Behold.... This online shop sells a backing for your photos that is postal service approved and will make them sturdy enough to send in the mail as a postcard. It comes in 4x6 and 5x7, and its affordable! Even for cute young broke and married people like me! You can get 50 for less that $15!
