I like all types of cards nice ones that is select with love :-)
But also cards of the place or country where you come from.
I also like it if you write anything about your place.
And I like to find out something about you, such as where or how you live and what your interest in.
It is also nice to know what the weather is in your place.
I recently received a card where it's indigated with a thumbnail image as cloud with snow flakes and temperature.
And of course, something written in your language and what it means.
