i knew that it would be past halloween when eric received his exchange envelope so i wanted to do an example that showed how you could do very, very, sloppy lettering and still make it look fun. the france is not finished. it shows chunky letters made with highlighters. then the name shows an outline that leaves some space and some mouths and a few dots.
it's playful. you could do other kinds of doodads.
you really do not need to be good at lettering to do fun envelopes.
maybe leave a little extra space between things....
and have the address lines small, and easy to read.
