Jessica, here is the Cactus Flower block. It measures 9 1/4" before the sashing. You can trim off however much you need to to make it work for you. I added the floral fabric from my own stash to match the lighter blue in the "diamond" fabric.
If it's too blue for you, let me know and I can finagle it a bit.
Here's the test block
Pinks, purples, white, yellows and greens.
Let me know what you think.
If you like it, I'll send it along asap!
Happy New Year!
