Introduction to Botanical Drawing I | September 3, 10, 24, October 1 | IN-PERSON
This class is designed to provide foundational drawing skills and inspire a sense of wonder and connection to the natural world. You’ll learn to think like an artist, get curious, ask questions, and play — all while learning how to draw. We start with an overview of botanical art and learn about the benefits drawing provides for the brain and our physiology. Drawing habits and dealing with the inner critic are also discussed. Using pencil marks on paper, participants explore sketchbook work, basic line qualities, light on forms, and transforming reality into three-dimensional illusions. Sketching, contour drawing, negative space, and measured drawing are also covered. Experimentation, questions, and observations are encouraged in a relaxed and inspiring environment.
Instructors: Stephey Baker & Claudette Baker
Prerequisite: None

Botanical Drawing II: Shading & Structure | October 2, 9, 23, 20 | IN-PERSON
This course takes the next step in your artistic journey, sharpening your ability to see subtle shifts in light and shadow while deepening your focus and observational skills. Using graphite, you’ll explore grayscale rendering and value mapping, learning to blend smooth transitions between highlights, midtones, and shadows, resulting in refined, visually rich botanical drawings that convey structure and realism. Nature remains our greatest teacher. Together, we’ll observe how light sculpts botanical forms, sketch directly from life, and refine our understanding of contrast. You’ll create a personal value finder, experiment with artistic tools, and gain confidence in shading in a supportive, engaging environment where curiosity and practice make learning fun.

NEW! Botanical Illustration Intensive: Gorgeous Gourds in Colored Pencil | October 22 | IN-PERSON
Nothing says “October” like ornamental gourds. Striped, curved, bumpy, and beautifully colored, these small “sculptures” make great botanical art subjects. In this one-day “intensive”, you will study gourd characteristics, texture, and patterns to put together an interesting composition. Use texture techniques and color maps to create your composition – from underpainting to layers of colored pencil to finishing details. Application of watercolor washes, baby oil, or alcohol blenders are optional.

Botany for Botanical Illustration | October 31, November 7, 14, 21 | IN-PERSON
Botanical illustrators need to be well versed in the intricacies of plant form. Morning sessions help you learn to understand the structure of flowering plants and to study and draw a diversity of plant parts under the guidance of a botanist, John Hayden. Students keep an illustrated study journal. Scientific names in botanical illustration are discussed and used. In the afternoons, students will practice close observation of the plant specimen provided and produce a different graphite drawing to be included in each students’ portfolio with Sheila Hayden. Emphasis is placed on observation, accurate representation of details and labeling.
Instructors: John & Sheila Hayden

Introduction to Botanical Drawing III | November 12, 19, December 3, 10 | IN-PERSON
In Part III of the introductory botanical drawing series, you continue to draw inspiration from nature while building on the foundations established in Parts I and II. You deepen your observational skills, refine your interpretations, and develop greater precision in your drawing. This course guides you in translating what you observe into marks on paper, creating the illusion of form and cultivating a deliberate drawing practice. You study both natural and artificial light, exploring how light direction and color temperature influence depth, realism, and form. Through guided exercises, you refine your graphite shading techniques, sharpen your artistic eye, and create small color-matching studies using colored pencils.

NEW! Botanical Drawing: Mixed Media Explorations | December 4, 11, 18 | IN-PERSON
This three-session studio intensive is a deep dive into color relationships — observing, interpreting, and marking with greater fluidity than you’ve allowed yourself before. Working with graphite, watercolor washes, and colored pencil, you’ll slow down and study the nuances of hue, value, and light that everyday looking skips past entirely. Color asks more of the eye than greyscale ever does: every hue carries its own inherent value, and nothing renders true until that relationship is actually seen — through sustained, focused attention, which is in itself a visual art technique. Join me as we study early December light — remarkably different from late winter, early spring, even summer. Sessions move between indoors and the field, weather permitting, so dress for the season.
Instructors: Stephey Baker & Claudette Baker
Prerequisite: Introduction to Botanical Drawing III or Color Mixing
Required/Elective: Elective
NEW! Seasonal Greens in Colored Pencil and Micron Pen | December 9 | IN-PERSON
‘Tis the evergreen season: Holly, Pine, Juniper, Magnolia… In this one-day “intensive”, choose your subject(s) and create a “plant portrait” to frame or scan for commercially produced holiday cards – or draw/paint directly on blank greeting cards. Add a handwritten greeting as desired.

Guest Artist Workshops
NEW! Creating a Sense of Depth in Illustrations: Methods and Strategies with Rogerio Lupo | July 8, 15, 22, 29, August 5, 12 | VIRTUAL
Harmonious composition, precise outline, and accurate shading have immense importance as components of a great illustration. However, conveying a good sense of depth is not secondary at all. Every artist eventually faces the challenge of having to deal with the nuisance of a flat result – meaning lack of perspective or three-dimensionality.
By observing landscapes and distances, one can draw inspiration to use the effect of atmospheric perspective and represent the proper scale of contrasts and neatness. Combining a few or all of those diverse resorts is also an option, so that the different challenges can be cleverly sorted and all possible solutions reconciled.
In this course, we will study the theory and the empirics behind those methods, examine examples of masterful illustrations, and mostly proceed to live demonstrations using graphite, colored pencils, and even a bit of pen and ink, to explore and apply all the procedures available for the purpose of obtaining a convincing and eloquent sense of depth.
Instructor: Rogerio Lupo
Prerequisite: None
