Height:
Height is an often missed opportunity when decorating. It is space most of us have more of (and who doesn’t need more of that?) but usually forget is there.
In this example, elevating the plant takes it from ordinary to celebrated. 
Practically, it leaves a spot for a good book, during one of those relaxing bubble baths we all dream about. Sigh.
This collection of bath sundries looks cluttered in the first arrangement. Corralling these items on a pedestal looks more cohesive, frees up coveted counter space, and is easier clean, all while keeping necessities within reach.
Do you have unused space above a bookshelf or cabinet? Originally, I placed the large metal tile and oval mirror above the bookshelf simply for storage, while they were in between landing spots. 
However, I grew attached to them there and how they took advantage of the high ceilings, so I’ve only added to the display.
Hang curtains higher than the window’s top to draw the eye upward and add height to a room. 
Most floor-length curtain panels are 84 or 95 inches (with 108″ and 120″ available on more specialized sites). When buying new curtains, measure the distance between the top of your window and the floor, and purchase the next size up. To determine where to mount the rod, place it above the top of the window at the height which allows the bottom of the curtain to just dust the floor.
I consistently have more treasures than I have landing spots. Surely, I’m not the only one.
Height to the rescue!
So, go ahead, use that highest point to be your crowning moment and culminating point.
[A note about dust: For some of you, dust killed this design principle before you made it to the second paragraph. To you I say, first, life is short. Might as well let your meaningful possessions be a part of your everyday life, even if that means you have to step on a chair to dust, once in a blue moon. Secondly, I’m highly allergic to dust and have learned from many a sinus infection: The primary issue with dust is not it’s existence (which can never be entirely avoided), but the stirring up of dust. So, make peace with it. Who can see it all the way up there anyway?]
