Grosgrain

Grosgrain (pronounced grow-grain) is a type of fabric characterized by its distinct ribbed texture. The ribs, or cords, are formed by heavier weft (horizontal) threads that are tightly woven, creating raised horizontal ridges across the fabric's surface. This distinctive weave provides grosgrain with notable durability and a somewhat stiff or firm hand.

Typically, grosgrain is made from silk, rayon, nylon, or a blend of these fibers, though cotton versions also exist. The close weave makes it a relatively dense and strong material. The width of the ribs can vary significantly, ranging from very fine, subtle cords to wider, more prominent ones.

Grosgrain ribbon is a common and widely recognized form of the fabric. It is frequently used in millinery (hat making), garment trims, gift wrapping, and scrapbooking. Its structured nature allows it to hold its shape well, making it suitable for bows, embellishments, and other decorative elements. Beyond ribbon, grosgrain fabric is employed in waistbands of skirts and trousers for reinforcement and shape retention, and in the binding of seams to add durability.

The name "grosgrain" comes from the French "gros grain," meaning "coarse grain," referring to its prominent ribbing.
