Are you sure you want to signup for Used Postcards by Theme?
As a member of Postcrossing you often receive postcards you can't add to your collection. Rather than throw them away, send them to someone who will appreciate them.
For this swap you will send your partner - only ONE partner:
At least 5 used (i.e. stamped and written on) postcards in an envelope.
Try to send cards your partner has in his/her wishlist. Swappers that don't have any "Postcard Wishlist" in their profiles will be removed from the swap.
Postcards are not to be torn or badly postally damaged. They must be in a fairly good condition, i.e. the kind of thing you would be prepared to add to your collection.
