I saw a photo of something like this on a website, and thought it was such a great idea! Here is how I did mine:
I used Google maps to map my address to where I am sending my letter to.
Then I saved the image as a pdf and printed it out larger then I needed it.
I put glue stick on the back of my envelope and stuck on my map, and then trimmed the edges.
I wrote my return and sender addresses on address label stickers and then cut them out. ( I have whited out the addresses on here)
I lined them with black marker so they would stick out, and stuck them where they go.

All finished! Adorable personalized envelopes!
