It’s fun to combine collage and drawing. The illustrator Saul Steinberg turned cut-out pieces of graph paper into skyscrapers by pasting them on paper and drawing buildings, cars and people around them with pen and ink. He called it Graph Paper Architecture. The great thing is that his graph paper looks drawn, since it doesn’t shine like a magazine photo.
Exercise: Make your own version of Steinberg’s graph paper skyscrapers. If you don’t have graph paper, Sudoku’s, word puzzles, cryptograms or even text fragments (maybe upside down) from a newspaper are also suitable.
