This paper introduces a visual tool that facilitates engagement with speculative design futures while exposing the boundaries of understanding. Building on the Future Archeologies Method, the canvas guides participants through tactile speculation, scenario-making and reflection via eight components structured around a Line of Speculation. We tested the tool in two workshops with community members and futures experts. Results suggest that the canvas (1) accelerates the process, (2) supports collaboration, and (3) enables accessible yet radically creative futures thinking.
