This research project explored how natural phenomena influence textile expressions over time and aimed to develop alternative approaches to textile design and use. It investigated how textile lifespans can be adapted to their intended use, opening up to diverse rhythms of change that align with sustainable practices. Through this lens, the project reimagined how fiber properties and structural design can interact with environmental elements to shape textiles that evolve over time. The project consisted of a core long-term experiment documenting the transformations of textile samples exposed to organic matter, followed by an analysis of changes in colour and expression. The outcome is a material library that exemplifies these principles and contributes to a novel framework for co-designing responsive, temporal textile systems with nature.
