I love making ATC's. I started swapping with a small group about a year and a half ago. It has been a lot of fun and I have so enjoyed getting to know these wonderful ladies. The most cards I have made for a single swap is 10. Each one a little challenge on it's own, to come up with a design that I am happy with on such a small canvas, but so rewarding. Here are some of my cards.
Literary ATC
Black and White, and one color.
Childhood Games
Valentines
A Child's Christmas
