An improved method of forming a decorative panel of molded plastic comprising the steps of constructing a form having a detailed masonry surface; covering the detailed surface with a mold release material; applying a thin layer of gel coat over the mold release; applying a plurality of layers of fiberglass matte and resin over the gel coat layer; allowing the plurality of fiberglass matte and resin layers to harden thereby forming a heat resistant mold having a female side being formed against the detailed surface and a side opposite from the female side; removing the mold from the form; perforating the mold thereby providing fluid communication between the two sides; connecting a vacuum apparatus to the side opposite of the mold; placing a sheet of high impact plastic above and adjacent the female side of the mold; activating a heater thereby heating the plastic sheet to a pliable state; activating the vacuum apparatus thereby drawing the plastic sheet into the female side of the mold; and removing the formed panel from the mold.
