- Find a typeface you like and type out the address in that typeface. Then use some kind of editing software to horizontally flip your text so it's mirrored.
- Print the address(es) on a piece of scrap paper.
- Turn the paper over so the address is face down on the envelope, and position the address as desired.
- Use a pencil or some other pointy object to color the back of the paper. You probably did something like this in elementary school.
- The address will (should) get transferred to the envelope. I've only tried this with an inkjet printer.
- Use a ballpoint pen to trace the transferred image.
I made splatters with some black India ink to make it look more authentic. Apparently I wanted it to look like it was done by someone really messy.
