To sum up during these three months I sold around 69 handmade postcards (counting only originals here, cause I lost the number of prints long ago ;p).
I completely made 78 of them, but I think I will continue making some even if there's no market anymore until I reach a beautiful number of 100. "100 postcards scattered in Korea" --> quite a nice title for an exhibition, don't you think? ㅋㅋㅋㅋㅋ
I have nine sketches so far that leaves me 13 to imagine more.
