João Pereira from Igreja Cristã Manancial de Águas Vivas in Portugal brings us this nice use of fabric.
To create this they simply purchased some silky fabrics in two colors (their church logo colors). Then they bought the same type of fabric in white to back their stage.
The bunched them at one end and let them hang naturally at the other. Then they lit the whole set with LED Par 56 lights and 3 LED bars.
