I may have created a monster when I started including these tiny envelopes and letters in my mail. It’s caught on with my Correspondents, and the Tiny Letter Revolution is now necessitating having a magnifier at hand for reading my mail. :D 
Currently in the earholes: 
What fun!
Great cursive font you’re using here. What writin’ iron?

Do I need bust out the Micro 15 printwheel next time? Might be a fun little exercise… -Mitchell
Good to know my letter got to you OK!
You think reading those tiny letters are hard? Try writing one. Only my PDP-125 can type small enough for those letters, & that thing is about as unruly as you can get! Sometimes it’ll just turn off randomly, completely screwing up your letter!
I hope you enjoy those films, I made sure to include only the best-of-the-best on the list! Also hope the archive.org links help; a lot of those films are quite hard to find elsewhere, at least in any form of watchable quality.
Also also, good to know you got my Morse code message! Was it worth it? Probably not.
