Thread Between Us re-imagines the humble plastic bottle as both medium and message. In this pavilion, cast-off containers pass through successive states—shredded into luminous “threads,” sliced into roof-top rain harvesters, fused into ground-level “green vessels,” and tinted to form structural panels—revealing an evolving material ecology. Visitors move through these layers of transformation, tracing a circular journey from waste to resource. By choreographing the recycling cycle in real time, the installation turns architecture into a teaching tool: every surface shows how color, form, and function can be extracted from what we throw away. Thread Between Us invites Seattle Design Festival 2025 audiences to reconsider plastic not as refuse but as a renewable palette—and to imagine cities woven from the materials we already possess.
