“I Left My Heart in San Francisdough” is a hand-lettered, hand-drawn project by Olivia that explores the best sourdough bakeries across San Francisco while telling the process of sourdough fermentation. Through an urban map, the project educates viewers on the natural fermentation process and highlights the cultural significance of sourdough in the city. Olivia uses illustration and hand lettering to create a visual identity that brings sourdough to life. Her goal is not only to celebrate the artistry and science behind sourdough but also to inspire others to start baking it themselves. The visuals extend across different products encouraging audiences to connect with food, one loaf at a time.
