This template was designed by Carolyn Dickenson, who also made this incredibly beautiful ATC card sample. Carolyns ATCs are fantastically artistic. Her photobucket site is listed on the template sheet. Carolyn has allowed me to create the template sheet and share it with others. Many thanks Carolyn!
