I would take my cue from the picture if that is the look you are going for. If the color is neutral. pick a neutral. dark/solid looking/not busy , pick one of those. Don't be afraid to add one of your own in there if you cannot find one from this group. If it was mine, I would want a less busy fabric for the background, but that is JMHO. I think the star would stand out more. How about finding a floral that has a bit of another color in it to tie them together:red or green?
Also looks like they have repeated fabrics...Center fab matches row 5 (right after the cream), and so on. If you did that, you would not have to pick out so many! let us know how it goes...
