Jordane Saget is a chalk artist who roams the streets of Paris to draw his arabesques on the ground or on the walls. His wavy chalk lines have gradually established a dialogue with the inhabitants, to become today one of the markers of Parisian street-art. With this artist, we address the ephemeral nature of the chosen material, but also the aesthetic possibilities offered by erasing. Finally, we will come back to the importance he gives to meeting the public, to the point of wanting to focus his new work as close as possible to people, by working on their windows.
