Gravity of Happiness explores the transformation of soft fibers into hard structures, challenging the conventional perception of fiber as a soft, flexible material. This project focuses on how materials can carry emotional weight, turning the intangible feeling of happiness into something physically present. Through sculptures that shift from soft to rigid, I invite viewers to experience happiness in a new way—by engaging with the unexpected hardness of fiber. The goal is to create interactive, tactile pieces that not only question the nature of materials but also make joy something you can physically feel and connect with.
