Debora Stewart – The Foundation of Expression: Underpainting and Expressive Mark Making (Online); Friday, October 23 – 11:30 am PT / 2:30 pm ET / 6:30 pm UK Time

Date: Friday, October 23, 2026

Time: 11:30 am-12:30 pm Pacific time (2:30-3:30 pm Eastern time/6:30-7:30 pm UK time)

Level: All levels welcome

Medium: Pastel, acrylic, oil

Presentation Type: Talk / demo

Discover how expressive underpainting and mark making form the foundation of my creative process across pastel, acrylic, and oil. In this demonstration, I’ll show how energetic washes, contour drawing, and intuitive marks establish movement, structure, and visual interest before a painting begins to take shape. You’ll see how these same principles can inspire expressive florals, abstract gardens, figures, and abstract paintings, regardless of the medium.

Free!

Register once to access all events. Your Festival Pass includes Zoom links to the full schedule plus access to recordings, so you can revisit sessions or watch anything you miss.
