“Plein Air Workshop at Tlaquepaque – How to add people to your paintings!
with Gretchen Lopez

March 27 and 28, 2021  |  10:30 am-4:00pm  |  Sedona’s Tlaquepaque Artisan Village

We’ll be painting in plein air with the beautiful Artisan Village of Tlaquepaque in Sedona Arizona as our backdrop. Learn how to paint people into settings and cafe scenes, using an impressionistic approach with palette knife and brush. People add scale, life and movement to a composition, while also creating a psychological focal point to the work. The charm of adding people to your plein air and architectural studies will become a new tool to literally enliven your work!

Only basic materials required with your own plein air painting set-up.

Gretchen Lopez

Gretchen Lopez majored in advertising and design, when she attended Ventura College, then went on to study fashion design and illustration at the Fashion Institute of Design and Mechandising in Los Angeles. She completed her studies at the Art Center College of Design in Pasadena, California.

As a tenth generation native of California, Gretchen has a rich family heritage. She is a descendant of the first Spanish settlers of what was to become the Mexican Rancheros, her colorful family background includes Chumash and Apache Bloodlines. Gretchen’s works are greatly inspired by her ethnic heritage. Being experienced in many mediums and techniques allows her to express a feeling of freedom, vibrancy and spontaneity through color and design to depict the varied faces, fabrics and gentle beauty of Native and Hispanic women in her paintings.

She combines traditional as well as comtemporary elements in her works, from the figurative to still lifes. Gretchen resides in Northern Arizona, where she pursues her love of paitning. A teacher of painting, life drawing and portraiture at the Sedona Arts Center in Sedona, Arizona, Gretchen was nominated for the Viola Award for Excellence in Art Education. Her works are included in numerous private collections both nationally and internationally, and can be seen in select galleries throughout the Southwest.

Gretchen has taught me to paint far better than I thought I could! Her patience and expertise are reasons I take her classes on a regular basis.

I love Gretchens' teaching style and her ability to share some of her mastery with her students. I will keep returning to her classes!

Gretchen is a wonderful artist and a wonderful person willing to tirelessly explain techniques and share her knowledge.

Ongoing encouragement. Extremely supportive. I learn something new in every class.
