  • Catherine Watters demonstrating watercolor techniques to illustrate the delicate Californa Wild Rose, Rosa california

The Coast Live oak is one of my favorite subjects, and I come back to it repeatedly. Besides being a colored pencil demo of color choices, techniques and some tricks for painting the Live Oak acorns, my workshop will cover geography, history and some ethnobotany. The more you know, the more you see. The Coast Live Oak is truly California’s tree, iconic in our mind’s eye, on those golden California hills.

Donnett Vanek, Peritoma arborea (Bladerpod), Work In Progress. Drybrush Watercolor and Graphite, © 2023.

In botanical art, graphite and watercolor are sometimes used in one rendering to emphasize various parts of a plant.


Join artist Donnett Vanek as she discusses her rendering of a Peritoma arborea (Bladderpod) using this technique. In this presentation Donnett will take you through her steps of using two mediums in one rendering: how to choose which part of the plant to emphasize by using watercolor, while using graphite to compliment the watercolor.


Donnett will discuss the importance of a  cohesive composition when using both graphite and watercolor in one rendering.
She will also discuss her techniques for
both graphite and drybush watercolor.
This presentation is appropriate for artists
of all skill levels.
