Sonoma County artist Potenza has a big heart. Inspired by an act of charity 24 years ago, she endeavored to create ‘The Hearts of the World,’ a massive art project that has finally come to completion and includes over 200 paintings, one for every nation on Earth. Each piece commemorates its adopted nation through that country’s colors, flag design or other recognizable symbol, designed to bring people together through a message of love. Potenza exhibits many of these works of art and shares the inspiring stories behind them with a reception on Friday, Oct. 7, at the Journey Center, 1601 Fourth St., Santa Rosa. 5pm. Free admission. 707.578.2121.
