A blow-molded decorative article is disclosed which comprises a plurality of different polymers having different melt flow rates that cause inter-dispersion of the polymers upon blow-molding. The article is blow-molded from a multiple layer parison that a plurality of layers of like polymers, i.e., polyethylenes, polypropylenes, polystyrenes, etc., that have different melt flow rates and different colors. As a result in the differences in the melt flow rates, the polymers of the various layers mix upon blow-molding to create the look of a glazed ceramic pottery or an exterior pattern such as a tie-dyed marbleized or camouflaged pattern.
