I love the idea of anything that does double duty. That is why I love Prints on Chocolate.
The company can print any custom message on various types of chocolate. Below, they have these great escort cards that double as favors. The prices are fairly reasonable if you consider the costs of buying escort cards, calligraphy, and favors. Another idea would be to hand them out at an engagement party as a save-the-date.
Besides, who doesn’t love chocolate?
