Most of these were made for a group I got involved with - Posta l'Art, through www.art2mail.com
All postcards met the requirements for international posting - dimensions 4" x 6", no more than 1/4" thick and weighing no more than 10g.
I used a variety of techniques on my postcards.
All of my postcards were sent, as is, through the mail and reached their destinations in one piece.
I loved getting the other people's postcards in my mailbox while the swap was on! They are now displayed all around my home.
Why not make a postcard for someone today and send it?
