Although she takes inspiration from photographs, sketches, or rubbings of leaves or tree bark, she avoids using specific sources. "I'm painting about change, about a swamp where the morning light is very different from the afternoon, where the shape and composition 10 years ago aren't the same as today or 10 years from now," she says.

Stewart works on two or three paintings at a time because, she says, "I don't like to sit around watching paint dry." She uses opaque acrylics to move into what she calls "a more visceral, less conscious design activity, any gestural activity where I'm just throwing the paint around. Moving from one painting to another creates an energy, a conversation within and between the paintings."

She compares the last step of the process to a musical call-and-response pattern. At this stage, she adds medium to make the paint more translucent, then layers on the colors, with each successive layer answering the others in a manner similar to the way a tuba, for example, responds to a saxophone in a jazz band.

"It's a gestural composition in which the paint and the process are fluid," she says. "At some points, I need the paint to be in control. At others, I need to take control and make order out of the chaos I just created."

When she's finished, her passion to express and protect the organic beauty of life is always apparent.
