Warrick's career as an artist began after one of her high-school projects was chosen to be included in the 1893 World's Columbian Exposition in Chicago. Based upon this work, she won a scholarship to the Pennsylvania Museum and School of Industrial Art (now The University of the Arts College of Art and Design) in 1894, where her gift for sculpture emerged. In an act of independence and nonconformity as an up-and-coming woman artist, Warrick defied traditionally "feminine" themes by sculpting pieces influenced by the gruesome imagery found in the "fin de siècle" movement of the Symbolist era. At various times, she was a literary sculptor, at others a creator of portrait art - which she studied under Charles Grafly at the Pennsylvania Academy of the Fine Arts. Although she said that she could not specialize in African-American types, Fuller became one of the most effective chroniclers of the black experience within the United States. In 1898, she received her diploma and teacher's certificate.
