When you have objects that are fun to interact with, you want to keep them within easy reach. To create a sense of happy abundance, pack in as many as you can. Think of each item as a piece in a puzzle, and find the right fit in relation to others in the display. The bottom shelves can store small extras. For dusting globes, use a dry microfiber cloth (cleaning products could damage coatings). Three-tier steel-and-brass étagère, $2,800, lizobrien.com for info.
