Flocking is fibers, as opposed to embossing powder, which is just that... powder. Flocking is usually preferable for seat, door panel, and headliner applications. Lately, embossing powder is becoming preferable for carpeting and kick panels as it more closely resembles auto carpeting when applied. You can get flocking from Model Car Garage, Detail Master, Model Roundup, or Craft Stores. Embossing powders can also be found at Craft Stores or online.
