As I am a huge fan of alcohol inks, this is just another of many posts where that particular technique has been used to create the background. In this case, I used a standard sized sheet of glossy white cardstock, working on one large area. (You can scroll down to my post on 6/8 for details on the "brayer" technique used).
Then, when finished, I simply cut it up into several ATC's (2 1/2" x 3 1/2") and typically add collage items such as ephemera, embellishments and found items (mostly paper) to create these highly ADDICTIVE Artist Trading Cards!
