When I saw this ► card template ◄ I just to play around with it and come up with my own version.
This is the link to the original card.
First I created a card with the design cut out from magazine pages.
Then I saw ATCs that opened like windows and that gave me the idea for an ATC with the design embroidered on.
Next I had to try it with just paper. I created the design in my graphics program and printed it.
