I can add a border around the outside which starts to bring it out
see what happens now i insert a diamond shape in the middle
Add a couple more diamonds to increase the contrast
Again same pattern but another cutout this time in the middle tile,
a small terracotta piece to match the small outside corners
How Changing the internal to a diamond effect, completely changing
the look of the design
As you can see subtle changes to the design make a difference
Same as the last on but this time a nice border to match the
outside border
Last One just a few more changes from the last one, but scroll back
to the start to see how it can change to something more interesting
