Loma documents the scaling of mycelium biomaterials fromlaboratory cultivation to functional furniture through a case study in post-growth textile fabrication and public interaction. This pictorial presents a handwoven mycelium-cotton textile developed for exhibition-scale public use at Habitare Design Competition 2025. The work demonstrates a post-growth weaving strategy as a response to material constraints and biological irregularity. Through transparent documentation of successes and limitations, this project reveals current technical gaps: mycelium textiles at furniture scale require non-biomaterial backing and adhesive for structural stability, defining a boundary of current biomaterial practice. Exhibition data (43,000 visitors, sustained tactile engagement over 5 days) provides evidence of user acceptance. This visual documentation contributes transferable practitioner knowledge for designers integrating biomaterials into everyday objects.
