I sure hope so, Shannon, because I have the same desire to mix things up....and the same worries/difficulties as you, Suz, Ingunn, and others who've posted that they struggle with "how" to do this effectively.
Gaylene makes a good point about trusting your instincts. It's funny, but I have a painter/interior designer friend who told me the same thing: Trust your instincts. You know [what's right for you] better than you think.
Desire to mix things up is why I'm clinging to the style descriptor "elegant eclectic"....it covers a lot of bases and allows for a lot of deviation/experimentation!
