LSRUS: Unlikely Letter Swap

Hello Hello! For this swap, you will write your partner a letter on something that typically wouldnt be used for letter writing. You can be as creative as you like with this one, but just as long a it isnt on lined paper, printer paper, stationery or notepaper youre good! Some examples I've seen: A coffee filter, used envelopes, office planning sheets, toilet paper or kitchen roll.

Anything goes, so long as you can more or less read it and it fits in an envelope to mail! It's hard to calculate length with this sort of swap, so let's just say longer than 2 paragraphs please! Good luck!
