Like a ray of warmth offering relief from the frigid February wind, Sandglass Theater welcomes the 16th season of its beloved family puppet program, the Winter Sunshine Series. Every Saturday this month sees a new Vermont or Massachusetts puppetry troupe performing in Putney, with one-of-a-kind shows featuring everything from a stage that is also a suit to tales of activism in Indonesia. This week’s opening performance, Oma, follows a grandmother whose knitting tells stories, with a live score composed by Molly Gawler and the Gawler Family Band.
