Post-qualitative research-creation improvisations offer new possibilities to explore method/ology. In this article we question how bags, as seemingly mundane objects, work as ontologically lively matter – as active agencies – to choreograph human-nonhuman relations and heterogeneous materialities. Working from three questions – How might a bag become? What do bags do? What do bags enable and enact? – we discuss four research-creation improvisations and the insights they generated. The article maps how bags choreographies put affects, bodies and materialities into co-motional relations in order to disturb normative approaches to research both within conference sessions and through writing articles.
