So far the only scrappy I've done was the mystery train ride one. Being a bit of a control freak I sorted my lights, mediums and darks and then picked sets of nine that I liked together that had variety of both color and value in each set. The thing that gave it continuity was the sashing and using the same dark background multicolor print fabric for all the stars at the intersections of the sashing. I've since added borders which also help pull it together as well as increase the size. Will see if I can get a picture of it.
