Changeability in textiles is usually considered as a sign of low quality. The market is therefore overrepresented by designs intended for static conditions. When a consumed product starts to change, it is then often discarded. In opposition, this work aims to discuss how good quality in textiles can be a designed lifespan, where aging and change in materials are manifested as valuable aesthetic properties. Since all materials are somehow changing through time, there is a need to consider changeability in the designing, where the inherent properties of the material are of significance to a product’s development and design identity. This work has an artistic approach to sustainability rather than scientific, with an ideological perspective to be explored and communicated in the aesthetics. Through changing colors of natural pigments and through unraveling and reconstruction of dyed tricot forms, unconventional coloring and forming relationships are suggested in this project, portraying textile transformation. The intention of this work is to contribute to the field of interior design by suggesting a more sustainable relation towards textiles as changing materials, in a context where the boarders to the art and craft fields are erased.
