Letter not on stationary

Borrowing from @shinysherra

She hasn’t hosted this in awhile and I love this swap and I don’t think she will mind me doing it.

For this swap you will write a letter on anything that isn't stationery. Write a decent amount, not a short note. Some examples of things to write on are junk mail, a piece of cardboard, the back of a poster, etc. You can write about whatever you wish! You will have 2 partners. Write a letter to each.
