~~***Repurposed Drawer***~~ Give new life to an old dresser or cabinetry drawer. Line the inside with pretty paper and use picture-hanging hardware to hang the drawer on the wall. This drawer has a handy built-in divider that doubles as a second shelf. Screw in a cup hook along the bottom of the "shelf" to hang items from. Resource~betterhomesandgardens
