This is what I started with 2.5 inch square I cut up from scraps.
I pieced them into 9 patches. They were random. As long as they weren't the same print they got sewn together.
As you can see they get cut twice from the 9 patches you have sewn. Also they get stitched back together. I try and lay one block out to make sure I have the section laying in the order for stitching back together. So the more blocks in the 9 patch the more variety you have to sew back together.
