Last weekend, local artists will open their studios and workshops all over the city to the public during the 20th annual Somerville Open Studios (SOS).

Organized by the non-profit organization of the same name, over 360 artists participated in the admission-free event. Additionally, on Friday, May 4, some artists opened their studios as a preview of the event.

This year’s event was coordinated by Ellien Laramee-Byers, a photographer, illustrator, and part of the Somerville-based Mad Oyster Studios, pictured here.

Somerville Open Studios (SOS) is a non-profit organization formed for the purpose of producing an annual open studio and related events in Somerville, Massachusetts.
