What is the purpose of interfacing in sewing?

Interfacing is a crucial component in sewing that serves to enhance the stability and structure of fabrics, especially those that are soft or lightweight. When added to certain areas of a sewing project, such as collars, cuffs, or waistbands, interfacing provides support, ensuring that these features maintain their shape over time and during wear. This added stability is essential for achieving a polished and professional finish in clothing and accessories.

The purpose of interfacing extends beyond merely modifying appearance; it plays a fundamental role in the garment's construction. By reinforcing areas that may be prone to stretching or distortion, interfacing helps prevent issues that could arise from the natural drape of softer materials.

In contrast, the other choices do not accurately capture the primary function of interfacing. While color and texture may be considerations in fabric selection, they are not the main purposes of interfacing. Rather, interfacing is specifically intended to enhance the structural integrity of a garment, making option B the most appropriate choice for understanding its purpose in sewing.
