He uses watercolors to illustrate his children's books. He begins by stretching the watercolor paper over a wooden board. Next, he copies his rough sketches onto the paper in pencil. He is then ready to begin painting. For his backgrounds and blended contours, he uses wet paint on wet paper; this achieves a softer effect. For the finer details, he first lets the painting dry, and then he paints the final picture layer by layer. When the illustration is complete, he cuts the paper from the wooden board.
In February 2017, he was the featured speaker, author, and illustrator at Nepal's first children's literature festival, Bal Sahitya Mahotsav.
Marcus Pfister lives with his wife, Debora, in Bern, Switzerland.
