Have you ever tried tempera paint sticks? They’re what I used to sketch this face. It’s the foundation for what will be covered with bits of torn (and cut) paper. I love tearing pieces of paper then assembling them into something else. At this point I don’t know how much of the tempera face will show through the paper or how much I’ll leave uncovered. Everything depends on how the paper pieces and the paint react with the glue. It’s an exciting process!
