sentences:  Cookies can be decorated with more than one color of icing.This is accomplished by allowing the first color to dry completely (often for as long as 2 hours) before adding the second color of icing.While the goal is usually to keep the colors separated when filling in a design on a cookie with icing (such as the white of Santa's beard from the red of his suit), sometimes the colors or bled together on purpose to create a design such as a spider web design.
