Pongee is typically made from silk, and results in a textured, "slubbed" appearance; pongee silks range from appearing similar to satin to appearing matte and unreflective. Though pongee is typically made out of silk, it can be woven from a variety of fabrics, such as cotton, linen and wool. Originally pongee was hand woven.
