Emerald green velvet curtains add romance and grace to nearly any room. You can even use them as blackout curtains for your very own secret getaway. Velvet tends to dampen sound. The full-length curtains lend grace to a room, especially when contrasted with white sheers. Alternative uses include using them as drapes for a four-poster canopy bed or even as swag curtains for a throne in a theatrical production. Their rich, vibrant color will lend sophistication to nearly any room or occasion.
