Abstract: The present invention features a brim-shaping device for a baseball-type cap, a device that helps create and maintain the desired curvature of the cap brim. The shaping device is a mold that has a substantially hollow, curved body, and a curved, shaping slot for insertion of the cap brim into the hollow, curved body. The mold may have a number of slots running along the sides of it to allow for aeration of the cap when it is wet, so that the cap will dry more easily after washing. The hollow mold is shaped to present the cap at a given angle, so that the cap portion is displayed above the brim as it rests in the shaping slot. The given angle, usually approximately thirty degrees, presents a good angle for a viewing display. This angle also allows a washed baseball cap to drain of water. The mold itself is attachable to a display rack, so that the shaping device can also double as a merchandising tool during the sale of the cap. That is, both the cap and the shaping tool can be sold together as a single unit.
