Create a view of luxurious, full-length dark green velvet curtains that stretch from floor to ceiling, with a rich, deep color and a soft, plush texture. The curtains hang elegantly, with thick, heavy fabric that adds a sense of opulence and grandeur to the space. The velvet has a subtle sheen, catching the light and enhancing the depth of the dark green hue. The folds are full and flowing, creating a dramatic, graceful effect from the floor up to the ceiling. Behind the velvet curtains, add a layer of sheer, delicate tulle in a soft ivory or off-white color. The tulle should be light and airy, providing a soft contrast to the heavy velvet. It drapes gently to the floor, allowing natural light to filter through while maintaining a sense of privacy. The combination of rich velvet and light tulle creates a balanced, sophisticated atmosphere, ideal for a grand, elegant room
