It is well known that plastic shower curtains can develop mildew and/or mold where the curtain adheres to another surface and remains moist, such as the edge of a bathtub. A shower curtain with at least a portion of the surface being non-smooth is disclosed. In some embodiments, appendages extend outwardly from the surface of the curtain. The appendages prevent the surface of the curtain from adhering to another surface via surface tension of water. Furthermore, the appendages create an air gap that enables air to flow freely between the curtain and its adjacent surface. The appendages also reduce the surface area of the curtain in contact with the adjacent surface.
