Elodie Vally is a stained-glass artist. She was involved in restoring the Chartres Cathedral's stained-glass windows.
Three years ago, she took over the reins of the Ateliers Lorin. Founded over 150 years ago, this is the world's oldest operational stained-glass window-making workshop.
Today, she opens the doors of her workshop to show us what makes the blue of Chartres so special.
