Ooops! That isn't what it's supposed to look like!
I knew I wanted the orange to run through the middle and I'd been concentrating on that so I hadn't noticed that I'd sewn the middle strips in upside down. A quick session with the seam ripper, re-sewn and it was soon put to rights.
This block really needs to be joined with three others the same to make a lovely diamond pattern in a huge 24" square, but I'm just using this one to fill in my BOM quilt, but I do want to make more of these as they're such fun to make. I can feel another quilt coming on!
