Show and tell friends what you've been up to by turning your snapshots into postcards. Just glue a 4-by-6-inch photo to a color printout of one of our postcard templates then drop your customized card with a standard postcard stamp in the mail. Instead of receiving a generic shot of a tourist attraction, friends will see your vantage point or you and your family having a good time, wherever it is you may have vacationed.
