FemEdtech is a reflexive, emergent network of people learning, practising and researching in educational technology converging on the intersections of feminism, education, and technology. The FemEdTech Quilt of Care and Justice in Open Education was a collaborative quilting project emerging from the FemEdTech network. Through a posthuman lens, this chapter explores the lives and purposes of the FemEdTech Quilt assemblage, using makers’ stories of their quilt squares, images, and Markov chain poetry, alongside ‘unseen’ contributions such as the thoughts, feelings, readings, and memories articulated within a slow ontology of feminist praxis, that authors shared during Thinking Environment conversations.
