Centre square design
This centre square is made up of one image that appears four times. Three of the image segments are flipped vertically and/or horizontally so that all segments mirror each other.
Centre design created from original image segment (top right).
In this example, the original image appears in the top right segment. However, any segment can contain the original as long as all segments mirror each other.
Experiment by placing the original, unflipped image in different segments and consider how this changes the pattern.
