Do you do puzzles?
If you do, you know the feeling that inspired all those expressions about the pieces falling into place. With more and more done, you pick up the pace as you spot the right piece more quickly.
So, too, in decorating (or really, any large-scale creative venture with a million little pieces.) The more that has been determined, the less there is to be determined about what remains.
Friends, I am feeling that momentum in my house, and damn, does it feel good.
