Nubees blocks from Sept.

For a few weeks now I have had all 6 of my blocks from the September round of Nubees block swap, but realized that I hadn't taken a photo of all of them to post.

I have some ideas on how I want to set the blocks (maybe adding 1-3 more), but not sure what colors I am going to choose for the background of the quilt. I keep leaning toward grey, but am afraid that that's almost overdone at this point. Maybe the soft blue? I'm open to suggestions...
