I saw this project on a artolazzi.blogspot.com. Self Portrait in Space the final frontier this is so much fun to do. It was a total different way to do self portraits. My students really enjoyed doing them as well.
First I talked about how to draw the face right on a 9"x12" white paper. After we did this we painted them in.
Next they drew their space suits on a 18"x24" white paper. I show them pictures on real space suits. After that we cut a whole out for thier face. I know the place where I saw this they laminate the faces so it would look shiny.
