​When the house lights dim and a hush falls over the audience, all eyes fixate on one thing: the Grand Drape. Before a single line is spoken or a spotlight flickers to life, the stage curtain sets the mood. It is the boundary between reality and the world of the play.

​But stage curtains (or “theatrical drapery”) are much more than just heavy pieces of fabric. They are precision tools designed for acoustics, light blocking, and visual storytelling.

​The Anatomy of the Stage

​Most people know the “big red curtain,” but a professional stage is a complex layering of different fabrics, each with a specific job:

​The Proscenium Arch (The Frame):

​Grand Drape (Main Curtain): The primary decorative curtain. Whether it’s a “Traveler” (opens sideways) or a “Fly” (lifts upward), it signals the start and end of the show.

​Valance: The short, wide horizontal curtain that hangs in front of the main drape, hiding the hardware and adding a touch of elegance.

​The Masking (The “Invisibles”):

​Borders: Wide, short curtains used to hide lighting rigs and fly equipment from the audience’s view.

​Legs: Tall, narrow curtains on the sides of the stage that mask the “wings,” allowing actors to wait for their cues without being seen.

​The Backdrops:

​Cyclorama (Cyc): A large, flat, usually white or light grey fabric used to project light and colour—frequently used to create the illusion of a sky.

​Scrim: A magical fabric. When lit from the front, it appears solid; when lit from behind, it becomes transparent. It’s the ultimate tool for dream sequences or ghostly reveals.

​Fabric Matters: More Than Just Aesthetics

​Choosing the right material isn’t just about colour; it’s about safety and physics.
