Matthaus began sculpting at 5 years old; by 9 he was making animals and imaginary creatures using paper, paper towels, plants, clay, and even food. He began to work in tin foil because his sculptures are durable, but flexible enough to “roam” around in his imaginary world. Matthaus also enjoys working with ceramics and his playful and whimsical creations have made him well recognized; he has several run workshops at the Children’s Discovery Museum and entertains with his foil sculptures at events and parties.
