Simple Suminagashi - Lesson Plan I would tie in a Japanese Contemporary Artist name 'Yoju' - she does suminagashi and watercolor utilizing landscape, fish, and other animals. Show her artwork to the kids at: http://artbyoju.com/sumi5.html
Suminagashi (sue-me-NAH-gah-she) literally means “floating ink” and is an ancient form of Japanese marbling dating back over 800 years. Colored inks are floated on a bath of clear water and then gently manipulated into delicate patterns. Paper is carefully laid on top of the water to absorb the colors and then lifted. This is a form of monoprinting where no two prints will be exactly the same.
