The inspiration for Day of Discovery comes from fossils of pre-historical creatures and rocks inspired by light and shadow effect showcased in Harbin Ice Sculpture Exhibition. To have the patterns, I traced the outlines of prehistoric fossils and skeletons, making them appear like shadows on my samples. This project is aimed at the children's interior rooms market, so I used thermochromic fabrics and glow in the dark threads to enhance interactivity and educational value. These materials are safe for children. During the process of this project, I experimented with many materials I had never used before and discovered new methods to make textiles - for example, using thermochromic pigments for screen printing. Although it was my first attempt and I’m still not proficient, I found the process exciting. I hope to explore even more possibilities in textile design in the future.
