Thank you so much everyone.
I'm 99% sure of what I am going to do ... I saw a different layout of this pattern on pinterest:

So I'm going to use all the blocks, but I will buy (sigh, and I wasn't supposed to LOL) blue fabric to frame the blue flowers.
I love the middle one for the background for all of the flowers. And the purple fabric looks so nice against the purple / pink flowers.
I will post pics as I make progress!
