Text and Collage Swap: ATCsforall.com

This site is set up a bit differently- the swap was 3 for 3, and I made an extra card for the host. (On this site, you mail all cards to the host, who then redistributes them to the participants, usually based on skill or effort. You also pay for return postage, which keeps everyone honest, and usually weeds out the sticker slappers!)
