Sanchez Art Center and the Art Guild of Pacifica are hosting Pacifica Open Studios 2007, which opens Friday with preview benefit from 7 to 9 p.m. at the Sanchez Art Center, 1220 Linda Mar Blvd., Pacifica.

Works by 64 artists comprise the event, which features demonstrations and a silent art auction. Proceeds from the benefit go to Sanchez Art Center; tickets are $25.

Later, on Saturday and Sunday from 11 a.m. to 5 p.m., the same artists — working in media from painting to photography to sculpture, ceramics and glass — participate in Pacifica Open Studios, showing their work in an “open walls” experience at the center, or opening their own workplaces to visitors.
