I would like any kind of postcards and knowing a bit about what's going on in your life, wherever you come from!
Love stamps, so would be great if you use multiple smaller value stamps than one full value stamp... I think stamps are like mini-postcards!
Feel free to send me postcards in German / French / Spanish / Portuguese - I could also reply back in these languages, besides English!
Doodle/sketch even if you don't write anything!
