Octagons

This design is made up of nine octagons, each stitched in a different three-color repeat
pattern.  One cover shows the design with each octagon stitched in its own three colors
and with the background stitched; the other cover shows the design with all of the
octagons stitched in the same three colors, with the color of the canvas for the background.
The design shows that any repeat pattern will look different depending on where
in the pattern the colors are used.  Also, the more contrast in the colors, the more
dramatically different the repeat pattern will look.
