Students at the Newton School in Strafford work on mosaic murals under the guidance of artist-in-residence Lizz Van Saun Tuesday morning. The four-panel project, made up of thousands of piece of colored glass, will adorn the school's entrance once complete. A grand unveiling of the final installation is planned for Wednesday, Dec. 18. Above, middle-schoolers Casey Yunger, Heidi Hewes, and Grace Solsaa place bits onto one of the four panels. (Herald / Tim Calabro)
