Mail Art: Liberate Your Art Postcard Swap

I'm participating in the "Liberate Your Art" postcard swap sponsored by Kat Sloma. We sent here five postcards featuring our original art, and we receive five back from artists all over the world! It's very cool. These are the first two postcards I received. The one of the left is from Petra Kern.  She lives on the other side of the world (Ljubjlena, Slovenia) and makes beautiful art in a style totally different from my own. The excellent zentangle on the right is from Karen in Idaho. She quilts, zentangles and art journals. So much fun to discover new artists and bloggers. Have you received anything fun in the mail lately?
