Yes, Yvonne. Those are the colors. Leaving them unattached is fine.
Barbara, your blocks are beautiful. Jane, I am so anxious to see.
As soon as I ship Yvonne's row to Barbara I am going to work on yours because I love 30s stuff. I haven't moved in 17 years and probably never will. But I moved every 6months or so as a child. I actually miss it. Some place new to decorate. A chance to throw out stuff you don't need and find stuff you misplaced the last move. It will come together.
