Above are some new ATCs (Artist Trading Cards) I finished today that I'm going to donate to my local art guild. The guild is going to package up some of the member's ATCs to trade at the upcoming Frisco Art Festival. ATCs are pretty fun and quick to do. They are a universal size of 2.5 x 3.5 inches. They are perfect for my short attention span. You can use any media that you want on them.....the sky is the limit. The only catch is that they have to be 2.5 x 3.5.
