I'm kinda adding the final details of my current project on the fly. Not always the best idea, but I usually don't design a piece completely from top to bottom ahead of time.
Take a look at the two pictures below...before & after. The first picture "before" shows the armoire as it was sketched out on paper. When I looked at it, I thought it looked naked. After some thought I added two pieces of molding. One on top of the bottom case, and one on top of the top case (crown). The second picture shows the "after".
It's amazing what a difference such a minor change can make to the overall appearance & balance of a piece.
