As a student Eckart worked with a manufacturer of Waldorf animals. He learned the importance of the simple form, the warm and natural material, and the absence of detail and anatomy in the preservation of harmony and children's imagination. After studying art and art therapy, Eckart went to Russia and worked in education for 12 years. He then returned to Germany with his wife and had four children. Now he focuses on making handmade wooden toys as well as building the agricultural commune Erlacherhof.
Eckart only uses hard wood found near his home, such as alder, birch, and cherry wood. He carves and sands the wood by hand, polishing the edges perfectly smooth to fit in little hands. The toys are then finished with beeswax and/or natural oil.
