This Kaleider Pattern Combo illustrates how Stencils can be used to blend Patterns and colors.  First, the Background was filled with a Diamond (Split) Funnel effect.  A rectangular Area was then added and sized to fully cover the image.  It was filled with a teal color.  A butterfly Stencil image was chosen and the Blend Stencil option was set.  Yet another rectangular Area was created, again sized to totally cover the image, and set to a grayish brown color.  The same butterfly Stencil was selected, again with Blend Stencil set, and then the Negative Stencil option was set.  Oval shaped Areas were added and positioned in each corner.  These were filled with a maroon color.  The same butterfly Stencil was scaled into each oval.  The Blend Stencil option caused the teal and maroon colors to mix, creating shades of purple.
