The Sulfuric Tunic, part of the Critical Textile Topologies X Planet City project, is a multimorphic textile-form, produced through whole-garment weaving. It embodies experimental design research that explores reversed crafting, zero-waste systems thinking, and complex textile behaviour. Its design incorporates notions of hyper-local manufacturing and circularity in a positive future-making context. Critical Textile Topologies is a collective of designer-researchers exploring new design expressions, processes and methods for critical understandings of textile-forms through questioning what materials, textiles, and form are.
