Does anyone know anything about the process of painting them or the material that has been used?
In this post Jeannie Szoradi mentions that for a performance of Cinderella the curtain was changed. Does this happen very often?
"The sunshine went into hibernation on Saturday, the second day of the ten-day festival. That did not seem to dampen the spirits of the audience, who entered the auditorium of the Mariinsky Theater to gaze upon a shockingly modern front curtain. Tonight, the flouncy blue-and-gold curtain by Golovin was replaced by a black-and-white depiction of New York City skyscrapers, thus portending an unusual night of dance from this usually ultra-traditional ballet company."
