Annette,
My advice is to start looking through magazines, quilt books and on the internet until you find a setting that appeals to you. There are a number of books published that deal with settings only. Spend the day in the library and pull out as many quilt books as they have.
I understand what you're going though. I have 12 redwork blocks finished but I'm still looking for that perfect setting. While I'm looking for that setting I make other quilts. :D Have fun with the search!
