About Kaesa...
I like quirky cards, beautiful cards, and of course cards that showcase something about where they are from. I love learning about history and science, so cards showcasing something about the environment or history of your area, architectural wonders, etc. would be awesome. I don't need location-specific cards, though; if you have a really pretty postcard or a postcard of something weird, I'm cool with you sending those too.
My French is not great, but I could use some practice, so a card in French would be cool! I'd also love a few phrases in your native language, if it's not English. Learning local slang is also cool. And I love drawings and doodles! (I won't judge you for stick figures.)
