There are so many layout and design options with the Granny Splits square!
This pattern will show you how to create a rainbow ombre version, but by simply turning, increasing rounds, decreasing rounds, or changing the colours of your squares you can put your own stamp on this pattern.
I recommend taking a look at some of the variations I have included before you start, as well as some of the examples made by some of my testers. You can also play around with a grid included at the end of this pattern to come up with your own ideas.
I look forward to seeing what you create!
