Mail art and Artist Trading Cards....

... Joined an online group:  Mail Me Some Art - a place to meet other folks interested in swapping mail art or ATC's.  Participated in one swap of ATC that the material had to include the paper from security envelopes.  If you have not looked.....there is such a diversity of colors and patterns.  Primarily black or gray, but easy to modify ....only limitation is imagination and size that cannot exceed 2-/12 x 3-1/2 {same as a playing card} Submitted to person hosting the swap and awaiting the cards I will receive in exchange.
