Weave decides what the finished bow does. Satin is soft and glossy and ties a full loop that drapes. Grosgrain is ribbed and stiffer, so it holds a crisp shape and suits anything handled or worn. Organza is sheer and layers over the others for depth. Curling ribbon is a different material entirely and will not tie a flat bow, so buy it only for curls.
