There's no end to the beach activities friends of the Blue Shutters find to fill their days here, and some are pretty obvious (sunny on the sand, body surfing, walks along the shore, kayaking). But here's one you may not have thought of: searching for sea glass that can be used to make jewelry. That's what Betty Hamilton does when she's here. You can see her work in an album at the Shutters, or online at her Mermaid's Tears website. And you can read about her in the news; her local NJ newspaper just did feature on Betty's work -- and mentioned her sea glass hunting in Glouceser.
