The first cardboard boxes I used were boxes that my art supplies came in. Some of the boxes came from significant events. Sometimes I would get a present and it would come in a box and then I would make a maskWhen the sun went down and I was living in my studio, I could make art that didn't have major clean up, and that was traditionally more expressive, I guess. I could use my hands, I could get paint on my hands and wash it off easily. It allowed for a different kind of freedom (Mark Grotjahn interviewed by Ana Vejzovic Sharp, Los Angeles, August 18, 2012).
