Abby posted a great tool for determining your style in less than a minute but if you're still stumped, take a look at some of these ideas:
Rustic Modern or Modern Farm
Traditional With a Twist from Domino.
If none of these fit your sensibilities, don't despair, there are hundreds of different styles (including the one you create for yourself). Peruse through house tours and pictures that have inspired us.
Let us know where you get your inspiration and what style you're gravitating towards.
