Painting Grapes on Vellum in Vienna, Austria
Saturday, May 31, 2025
Learn my approach to painting on vellum in this one-day workshop at the Botanical Garden of the University of Vienna. We will be painting a small cluster of grapes - concentrating on seeing and painting the colors in the grapes, mixing browns for the stems, painting the texture of the stems, and painting the cloudy bloom on the grapes themselves.
This class is designed for students new to vellum (learn how to successfully paint on vellum) as well as for more experienced vellum painters (learn new tricks and techniques and bring your work to the next level). The workshop combines demonstrations, discussion of materials and techniques, hands-on time for developing skills, and lots of individual attention and feedback.

Painting Spring Flowers on Vellum in France
Clos Mirabel
April 18-25, 2026
(Wednesday is a free day to explore the area on your own)
Limit: 12 students
Cost: $500 (class only - I will invoice you through PayPal)
Learn my approach to painting on vellum during this five-day workshop at the beautiful Clos Mirabel in the south of France. We will begin by doing some exercises on small bits of vellum to learn technique and to get a feel for painting on this surface. Then, we will explore the grounds of Clos Mirabel to choose painting subjects – roses, hellebores, poppies, columbines, fruit trees, iris, and so much more will be blooming this time of the year. If we are lucky, there may even be a few vegetables ready in the kitchen garden.
This class is designed for students new to vellum (learn how to successfully paint on vellum) as well as for more experienced vellum painters (learn new tricks and techniques and bring your work to the next level).

You may also choose to do a Hoefnagel-Inspired painting of the treasures you find in the gardens. Experienced vellum painters can use this as a studio class to work on anything they like.
