From left, Kristin Hathhorne and Patty Kermoian check out a backpack made of sewn leather at a new exhibit at the Sheldon Museum featuring handmade items by Rebecca Brewer and Adrian Revenaugh. Brewer's creations, including a salmon-skin satchel and hats, are made largely from materials found in nature, including bone, rock and wood. Revenaugh's works include many from recycled materials.
