And if those floral blocks had been cut up, I doubt KarrynneStorm (op) would have even had to post the question as it would be obvious HOW the blocks were pieced.
The genius in this version - and kudos to Jenny - is that the construction is camouflaged, and by using a larger scale print (whole) - the movement from block to block - or even patch to patch - is very subtle.
After admiring the overall effect, you keep squinting at it and tilting your head thinking it's pieced one way, but then you notice it can't be and you look for another way.
Just look at all the suggestions on this thread.
That would not be the case if you made up the floral block from smaller patches.
If you look at all the majority of C&B and Batik Waves and OceanWaves (different but same concept as the C&B) blocks, they all have med to high contrast between the patches.
It allows them to join like fabric to give the appearance of a larger block.
