Upholsterers working at the opera house don’t only deal with providing furniture with covering. They also make curtains, elements of scenery made of tull, horizons, wings’ upholstery. They use a few square kilometres of fabrics per production. Apart from those working in the workshop, there are also upholsters responsible for putting what their colleagues produced in place on the stage. There are creepers made of sponge, sisal lawns, and furry floors.
