Eden Cornelius – Field Instructor
Growing up homeschooled, Eden first found the primitive skills community in upstate NY through enrollment in a program called Primitive Pursuits at age seven. From that time until her teen years, she participated in programs through a number of organizations and attended primitive skills gatherings. In her teens, her time was spent hiking, camping, backpacking, cross-country skiing, and filling her journal with detailed sketches and facts about the wildlife around her.
All of her free time was spent outdoors, building debris huts, making cordage, and adventuring in the forest. Schooled by her fiber artist and aspiring naturalist mother, her love of the natural world was fueled by a rich curriculum with a focus on hands-on learning and her intense interest in insects and plants.
Now, Eden is a multimedia artist and painter who continues to share and learn skills, with a particular passion for pottery, wet felting techniques, needle felting, and natural pigments. With a background in youth leadership, she enjoys working with groups and fostering a creative connection with the earth.
