Oops! I spelled it wrong. It's actually grosgrain ribbon. Here is the description from Wiki. Hope this helps. :) Grosgrain (pron.: /ˈɡroʊɡreɪn/), also gros-grain and, rarely, gros grain, is a type of fabric characterized by its ribbed appearance. In grosgrain, the weft is heavier than the warp, creating prominent transverse ribs. It is called a "corded" fabric since the weft resembles a fine cord. Grosgrain is a plain weave corded fabric, with heavier cords than in poplin but lighter than in faille.[1][2] Grosgrain has a very dull appearance with little luster but is very strong.[3] It is a firm, close-woven, fine-corded fabric.[4] While grosgrain fabric is generally black, it can be many different colors, and grosgrain ribbon comes in a large variety of colors and patterns.
