During Blogfest, House Beautiful's panel discussion centered around "Aha!" moments in design. They encouraged us to think about our own "Aha" moment and blog about it.

I think my major "Aha" moment in designing my own home is when I took the plunge and painted my dining room cobalt blue. I had been thinking that I needed a rich but bright color to set off my white pagoda mirror and abstract art, and finally summoned the courage to do it last year . . .
I couldn't love it more, and it makes me happy every day when I walk through my front door. My "Aha" moment was realizing it's sometimes the small things like a paint color that can make all the difference in a space. 

What has been your "a-ha" moment in design?
