Artist Trading Cards, or ATC’s are basically baseball cards for artists. They measure the same size (2.5 x 3.5 inches) and fit into a baseball card sleeve. They provide the artists with tiny spaces of creativity. They are easy because they are small and give you lots of practice with techniques. Best of all, there are plenty of people who enjoy trading ATC’s. The best place that I have found is atcsforall.com. You can also use your trading cards as business cards, greeting cards or fancy tags for gifts. Here are a few that I made for the Princess Party. I will definitely be making more!
