Mark Making

Mark Making

Saturday and Sunday, February 15 & 16; 10am - 4pm

Instructors: Diane Williams and Chuck Potter

Mark making is as distinctive as your fingerprint, adding a personal touch to your painting. Marks can energize a painting, or highlight movement, texture or direction. In this 2-day workshop you will practice abstract acrylic painting techniques that are enhanced by your personal mark making. Feeling stuck or that something personal or dynamic is missing in your painting? This class is designed to help you develop your signature style by identifying your personal and unique marks.

Venture with us into the realm of self-expression by identifying your own unique style. We will be exploring a variety of techniques using water soluble pencils, Sumi ink, charcoal, sticks, scrapers, and other mark making tools. We will also use stencils, stamping, special patinas and other applications to create multi-dimensional layering effects adding depth and visual interest. The results are alive, authentic and exhilarating. Unveil the mysteries of abstraction by practicing techniques in form, rhythm and motion. Each student will receive individual instruction and group critique.

Diane Williams and Chuck Potter both hold Master of Fine Arts degrees in Studio Art and Consciousness studies from John F Kennedy University in Berkeley. Additionally, both have studied at the University of Hangzhou China, incorporating calligraphy, traditional Chinese landscape painting and Chinese medicine with their western art practices.

They teach workshops in their Benicia studio and Arts Benicia, Concord Parks & Recreation, and have run several workshops at their mountain retreat in Greenville CA. They recently taught a 4-day workshop at the Pacific Northwest Art School on Whidbey Island WA. Additionally, Diane and Chuck were adjunct professors for National University and have mentored graduate students from John F Kennedy, University. Their works can be found in corporate, public, and personal collections nationally and worldwide.

Materials list

Acrylic Paint

We suggest you invest in good quality acrylic paints such as Golden, Utrecht, Gamblin or Windsor Newton. A good online source for supplies is or Student grade paints have a lighter pigment load and produce a less intense color.

Choose a variety of colors including warm and cool tones as well as opaque and translucent colors.

Quinacridone colors tend to be more translucent while cadmiums are opaque.

Manufacturers generally provide a color guide to help determine the opacity of colors.

Be sure to include the primary colors of red, yellow and blue, plus black and white.

Note that zinc white is more transparent and better for creating veils of color, while titanium whites are opaque for covering or blocking areas that have been previously painted.


Golden or Liquatex polymere mediums in gloss and/or satin (again may purchase online at Jerrys Artaramas or Dick Blick).


Bring a variety of sizes including round, flat and filbert (angled) brushes. In addition, bring several "chip" brushes which can be purchased in any hardware store. These are inexpensive house painting brushes. You will need 1/2 inch, 1 inch, 2 inch and 3 inches. Brushes do not need to be expensive and can be purchased at any art or craft store like Michaels.

Canvas or Multimedia boards

Please bring 2-4 canvas surfaces suggested size approximately 24"x 36" each.

You may bring stretched canvas or canvas board, the larger the better. If you bring stretched canvas please get the 1.5 inch side (not the thin student grade canvas). Obviously, if you are traveling by plane, or have a small car, canvas board is more convenient. If traveling makes bringing larger sizes difficult for you, put 3 or 4 smaller sizes together to create larger work (bring extra canvases to compensate for smaller sizes).

Although stretched canvases or canvas boards are already primed, please prepare your surface with 3-4 additional coats of gesso for a more professional surface.

Multimedia Boards

If you are traveling, multimedia boards are lightweight and store easily in your suitcase. They may be ordered online or purchased from us in class.

P.O. Box 836, Buford, GA 271-4753

Water containers

Any type of container to hold water such as cottage cheese containers or plastic food storage containers from the dollar store. I like 2-3 water containers at all times when painting.

Bring spray bottles for wetting your surface.


You may use large paper plates, wax paper or commercial palette pads.

Other Supplies

Paper towels.

Palette knives and rubber scrapper

Wiping cloth, sponges, etc.
