Curtains are typically hung in a way that they are fixed within the window frame and close to the glass, which provides effective coverage for the window while also maximizing light control and privacy. This positioning allows curtains to not only function as a barrier against light and temperature but also enhances the overall aesthetic appeal of the window area by creating a finished look. When curtains are hung in this manner, they can effectively block drafts and reduce energy costs during colder months, as they create a seal that minimizes heat loss.

The other options do not reflect common practices in curtain installation. For example, hanging curtains loosely without any contact with the window frame may result in less effective light control and reduce the overall functionality of the curtains. Likewise, a design that emphasizes adjustability may not be as traditional or common as a fixed position close to the glass. Lastly, curtains serve both aesthetic and functional purposes; therefore, stating that they are only meant for aesthetics overlooks their practical role in window treatments.
