I had been collecting plastic cards for a while before a student put this idea in my head. Mini paintings on credit cards. I had used them for smearing and glueing, they were sort of piling up. I slapped a layer of gesso on them and went to town with left over paint any chance I got. Here are some that I thought turned more successful than others. I might have 30 going on. I have even done a kids class at Shelby Bottoms Nature Center painting on credit cards, fun!
