Which type of trim is described as being used alone or as a header for fringes?

The type of trim that is used alone or as a header for fringes is flat banding. Flat banding serves as a versatile trim option that can enhance the design of various textile applications. When used on its own, it provides a clean, simple finish that can complement the overall aesthetic of a fabric. Additionally, when flat banding acts as a header for fringes, it helps to securely hold the fringes in place while adding a polished look to the edge of curtains, pillows, or upholstery.

In this context, flat banding allows for creative designs and color combinations, enabling designers to achieve the desired visual effect without overwhelming other design elements. Its functionality and adaptability make it a popular choice among interior designers when finishing textiles.
