I made these for a swap. Each heart is hand drawn, and the cards are collages with a plain Kraft paper, and two text pattern papers, the darker is 7 gypsies.
I am excited to see what the other artists created. The challenge in making ATCs is adapting a technique to a 2.5x 3.5 in size. Many patterned papers are too large for the format, creating a unique way to share talent in a compact size.
Have you tried ATCs?
