'dish' question for all my dish-lovin' friends.

It's always a race here to see who will hunker down in my french bread basket (which never holds bread, by the way) once placed as a center-piece on my table.
Today, it holds all 9 lbs. of our lovely Sierra. Do Not Disturb!

I have a 'dish' question for all my dish-lovin' followers.
When you decorate shelving with dishes, and you want to display tea and coffee cups, should you place them right-side up or upside-down on the shelf to avoid dust? Inquiring minds want to know. ;)

I couldn't find a photo of open shelving with the cups upside-down but this is close.

Or, should you just hang them like this?
