Sheer curtains are lightweight fabric window treatments that allow natural light to filter into a room while providing a degree of privacy. Made from materials like polyester or cotton, they come in various colors and patterns, enhancing the aesthetic appeal of any space. These curtains are often used in combination with heavier drapes or blinds to create a layered look. They are popular in living rooms and bedrooms, as they soften harsh sunlight and create a warm, inviting atmosphere without completely blocking the view outside.
