Such a hard question! I have given this a lot of thought and my answer is... the Kitchen! I spend lots of time in this area of the house, so naturally my mind is always thinking of new organizing solutions for this room. I drive my family crazy with my constant moving of things around to maximize space.
I'd like to know what is your favorite room to organize in your house! You can vote for your favorite on the right sidebar.
