MapEnvelope is a website which prints a map that you choose onto a fold-friendly envelope template.
The tool overlays dotted lines onto the Google map before you print it, so all you’ll need to do is cut out the template, fold it up on the lines and glue the edges.
Using MapEnvelope is quite simple. Enter an address, city, state, or landmark, then include an optional personal message. The web app instantly creates your printable template, complete with a satellite view of the location, the address, and your message for that personal touch.
