Scrounging for Indigo

I'm still looking for something I could call indigo, which is August's color for RSC.  Striking out bigtime, but today's my birthday, so maybe I'll treat myself to a trip to the quilt store this week to celebrate.  Once I get fabric home and cut a piece off, it's a scrap, right?

In the meantime, I played with blocks.  A couple more Ohio stars got made, and I had a new idea on arranging them.
By putting the light-background blocks in the center, and the dark-background ones around the edges, it should look like the center is glowing...

And just now it occurred to me that putting the darks in the center with the lights at the edges might look interesting, too.  Hmm...
In any event, I still have lots of blocks to make, and time to play with them, so no decision is imminent or necessary.
Who knows how many ideas I'll come up with before all is said and done?
And now, back to scrounging for indigo.  There must be a scrap in one of these boxes...
