After the minor, I continued exploring sustainable ink-making through a collaboration with Sanne ter Haar, who made a publication about Dutch vegetables and their seasons. Together, we made onion soup, focusing on the onion as a Dutch winter vegetable. Instead of discarding the leftover onion peels, we used them to create lake pigments for a screen-printed poster. The final poster shares the recipe for the soup and instructions for making the pigment. Through this project, we aimed to show how everyday waste can be transformed into valuable materials and how food and design can be combined.
