Oh, this was an easy one.
Postcrossing is one of my major hobbies now. I have shared it in my M is for Mail post.
"The goal of this project is to allow people to receive
postcards from all over the world, for free. Well, almost free! The main idea is
that: if you send a postcard, you will receive one back from a
random Postcrosser from somewhere in the world....The element of surprise of
receiving postcards from different places in the world (many of which you
probably have never heard of) can turn your mailbox into a box of surprises -
and who wouldn't like that?"
Two cards I received this week:
Lavender fields in France, but actually sent from China. And:
A lovely portrait from Germany.
