Olivia Casares, center, takes a look Tuesday at the mural “Sonder” in the hall of Bates Mill in Lewiston. The Edward Little High School freshman is one of 41 students from Lewiston High School, Tree Street Youth, Next STEP and ELHS who helped create four murals to complement the current Maine MILL exhibit titled “Who We Are. Who Are We?” Maine MILL Executive Director Rachel Ferrante said there is plenty more space in the mill complex for murals so she hopes to get more schools involved when classes open in the fall.
