Join professional illustrator Bill Singleton in his popular introduction to natural history illustration using gouache, water-soluble paint that is opaque. 

For hundreds of years gouache has been the main tool that natural science illustrators choose for botanical subjects because of its versatility and “editability.” Bill will demonstrate gouache using both white or toned paper, compare transparent watercolor and gouache, and teach rendering techniques unique to this interesting and classic illustration medium.

Harness your inner botanical illustrator as we venture virtually out into the hills and arroyos of Tumamoc to learn how to paint with gouache.


    On the Zoom web platform, Bill will begin the class at 9 am and teach through a combination so demonstrations and lectures.
