Gesture and Mark-Making in Oil and Cold Wax Painting
September 19-22, 2026 1-4:30Paint abstract pieces adventurously and intuitively in this workshop at my Portland, OR studio! We’ll work on oil paper and wood panels to create with joy and abandon. I’ll show you all the basics as well as many of my favorite techniques.
Cold wax medium is a malleable paste of beeswax, odorless mineral spirits, and resin. It mixes with oil paint to create a luscious surface that can be textured, smoothed, layered, incised, and scraped back. We’ll use a variety of tools to experiment with texture and layers. We’ll explore using lightweight papers to add collage elements that blend in and become part of the painting.
We’ll play with making bold marks, adding and subtracting elements as we go. We will cultivate a playful atmosphere, using this medium where there are no mistakes!
Whether you’re new to the medium or more experienced, you’ll find something in this workshop to inspire you!
The class is limited to four students, so you’ll have time for individual attention.
Kn95 or N95 masks required. I will provide comfortable Kn95 masks. Thanks for keeping us all safe.
