With two fifth-grade classes from the school in the center of Orsay, as part of the 2km4 initiative launched by SIANA Essonne.
In the fall of 2025, the children collected leaves from trees and plants along the 2km4 route. Using these leaves and egg cartons, they made sheets of paper.
They cut scales out of this paper and assembled them on burlap banners.
These banners represent the skin of the path where they walked, listened, smelled, breathed, and looked at the plants.
