Tuesdays, June 24 – August 12, 2026, 9:00 am – 12:00 pm
Enjoy the fun of painting “en plein air” — painting directly from nature on location, using the medium of your choice.
I will be demonstrating in water mixable oil, but you’re welcome to bring gouache, watercolor or acrylic as you choose.
Tuition $244.00 non members, members: $224.00
Location: Delaware Art Museum
2301 Kentmere Pkwy, Wilmington, DE 19806
We’ll meet on the Kentmere Parkway in front of the Museum.
Topics will include: finding a landscape subject and creating a composition; starting a painting; understanding value and edges; creating textures to suggest foliage, tree trunks, grasses and other surfaces; gouache paint handling; layering and adjusting the thickness of the paint; brush handling; paint mixing; understanding the color characteristics of hue, value and chroma; and mixing a wide range of colors from a simple limited palette. The class will include demonstration by the instructor as well as individual instruction at each student’s level of experience
Join us for relaxed summer mornings of painting in nature in the beautiful surroundings of the Kentmere Parkway
Suggested In addition to your materials:
Something to hold your palette and paper like a pochade box, field easel, or drawing board leaned against an extra folding chair; you can also work in your lap in a watercolor sketchbook if you prefer, and use a small folding table for your materials
plus whatever you need for 3 hours outdoors — folding chair, sunscreen, drinking water, hat, etc. (we will mostly be in the shade)
Suggested materials for Water Mixable Oil
Surface
Canvas panels, gessoed hardboard panels (for example: “Gessobord”), stretched canvas, or “oil paper” (for example: “Arches Oil Paper”)
2 at either 8×10 or 9×12 (larger if you like, but use larger brushes)
Brushes
I recommend stiff, long handled synthetic brushes for water mixable oil. Two lines I happen to like are the Princeton 6300 or 6500 lines of synthetic oil painting brushes.
Sizes
4 (1/2”) flat (ideally 2 of these), #2 (1/4”) flat , #2 (1/4”) filbert, #2 round
Palette
Melamine, wood or tempered glass palette, or a pad of disposable palette paper.
Painting/palette knife
Recommended: round tip elongated diamond shape, roughly 1 1/2” long
Water jar for cleaning brushes
Wet panel carrier, cardboard box or plastic bin for carrying wet panels, canvas or oil paper
Paints
I recommend Royal Talens Cobra, or Holbein Duo Aqua paints (preferably not W&N Artisan), order online.

I will be using a limited palette of five colors. You can bring other colors if you like.
