What is one of the benefits of flannel interlining in drapery?

One of the primary benefits of flannel interlining in drapery is that it provides extra body and shape to the fabric. This added layer enhances the drape of the curtains, giving them a fuller, more luxurious appearance. The flannel's thickness and texture help the drapery maintain its structure, making it less likely to sag or lose its form over time. This is particularly important in creating an elegant and polished look in interior design, where the way fabric hangs can significantly impact the overall aesthetic of a room.

In addition to shaping, flannel interlining can also contribute to insulation and light filtering, further emphasizing its value in drapery applications.
