People use hands to shape them and there are five steps in making a clay statuette, clay making, molding, shaping, coloring and decoration. The clay statuettes are colored in batch instead of one by one. For decoration, people use sorghum straw instead of brush to add colors, which usually include red, green, white, yellow, etc.
