I did manage to finish 4 Greek square blocks for the challenge.
Nine-patches are a Leader-Ender project, so I just slipped some aqua scraps into the stack.
There's more aqua/teal/turquoise scrappiness going on at Soscrappy's blog, so do take a few minutes to see what has inspired others. I think I'll go take a nap - maybe the sun will be out when I wake up!
