This article features a multilingual family literacy project to enhance family engagement in children's literacy development. First, the authors expand the emerging framework of translanguaging beyond the individual competency toward a collaborative practice across family/community members and diverse sign systems. Then, the authors describe how a multilingual family literacy project created a community translanguaging space that maximized leveraging of family funds of knowledge: collective community semiotic repertoires. Participating families (parents, children, and extended family/community members) collectively built larger communicative repertoires by connecting across individual linguistic, multimodal, and cultural capacities and experiences to create each unique family storybook. Finally, the authors provide suggestions on designing and implementing community-based family literacy projects.
