This article explores questions of critical ethics for communicating Indigenous craft practices through the lens of a project undertaken in Brazil in 2021–2022.The project was a collaboration between educators at the Royal College of Art, London, Universidade de Brasília, Brazil, and the Munduruku inhabitants who live in Bragança-Marituba, Pará, Brazil. It resulted in a “living” repository of craft practices and Indigenous Knowledge, incorporated into an online village library. The ethical and methodological questions this raised, especially around the issue of intercultural communication and critical librarianship, offered fresh ways of documenting the representation of Indigenous craft knowledge and traditional cultural heritage and point to how design history can be “owned” by a community.
