The projects were worth tens of millions. To avoid dependence on sponsors and patrons, Christo and Jeanne-Claude created land-art projects solely on their own income from the sale of sketches and prototypes. In addition, free viewer access was important for the artists, so admission to all projects was free.
"AN IMPORTANT THOUGHT IN OUR WORK IS THAT ALL OUR PROJECTS REPRESENT FREEDOM, AND NO ONE CAN BUY THEM... FREEDOM IS THE ENEMY OF PROPERTY!"
