The Anything Art of Jimmie Lee Sudduth (by Carolyn W. Ezell)
What would you do if you had a pile of sand, a chunk of clay, a piece of plywood, and a handful of leaves? Perhaps you would build a sandcastle and decorate it with bits of the clay and leaves. Maybe you would use your imagination to create something else wonderful and unique.
Jimmie Lee Sudduth is an artist who uses his imagination to paint pictures with the many things he finds in nature. Unlike most artists, Sudduth rarely uses canvases, paints, or brushes. His favorite painting surface is plywood. Instead of using paint, he uses clay, sand, soot, and such things as leaves, pine needles, and berries.
Sudduth has been painting since he was young. He is well known as a folk artist. Instead of going to art classes to learn their skills, most folk artists teach themselves their art forms and learn through years of experience. When Jimmie was young, he would sometimes draw pictures in the dirt if he could not find a board or a piece of cardboard to use. When he wanted to make a picture but didn’t have any paints, he made his own from the colored materials he saw in his yard and around his hometown of Fayette, Alabama. Sudduth especially enjoys painting pictures of log cabins, flowers, and animals. «I can paint anything I can dream,» he says. «Painting takes me anywhere my imagination goes.»
In 1976 Sudduth’s paintings took him to Washington, D. С where he joined in a huge folk art festival during our nation’s two-hundredth birthday celebration. Sudduth taught art classes to both grown-ups and children.
Usually he begins with a piece of plywood, which he holds in his lap while he works. Sometimes he uses other surfaces. In his studio you can find paintings on cardboard, old wooden shingles, and on pieces of floor tile. When he begins a picture, he surrounds himself with containers holding sands, soils, and clays. He likes to use white, gray, and brown sands as well as brown and black soils. He also uses white, gray, and clays. He prepared these by adding sugar and a little water to the sand, and syrup to the dirt and clay to help them stick to the board. Through the years Sudduth has collected many different colors of sand, dirt, and clay, most of them from the Alabama countryside. But people have also brought him unusual sands and soils from all over the United States. When he finishes a painting, he can point to the different colors in it, as though he were reading a map, explaining where he got each color.
He makes the color green for trees, grass, and flower stems by crumpling leaves and rubbing them back and forth in designs across the plywood. In the winter, when it is hard to find leaves, he uses fallen pine needles. To add purples, pinks, and blues to his work, he presses berries against the board.
Sudduth’s bright and colorful paintings are shown in folk art galleries from Washington, D.C., to Berkeley, California. Each fall he takes part in an Alabama folk art festival called Kentuck. During this two-day festival, he shows hundreds of people how to paint using nature. He says the most important parts of painting with nature are to explore the world with our imaginations and to have fun with creativity. His paintings make us aware of many things in nature that we often take for granted.
