Sunflower centerpieces

I am starting the 'Fun' DIY project of making my centerpieces for my wedding. I am having an October Wedding and my Bridal colors are Chocalate and Champange. I love,love,love Sunflowers so I have decided that they will be the main focal of my bouquet and Centerpieces.
Does anyone have any ideas on what you might think would look good with Sunflowers for the Centerpieces, Girls' bouquets and the guy's?
Any ideas would be so appericated!
Thanks
