This year is the 20th edition of Festival International des Jardins at the Domaine de Chaumont-sur-Loire in France. These special gardens are more vegetal art installation than a typical garden.
I noticed a common denominator on some of the photos of last year edition. They all have details suitable for entertaining. I thought that you might enjoy seeing them.
This teacup display could be something that you reproduce on a smaller scale for a tea party. It is pretty simple to build your own stand or to find a wall shelf unit at a store or at the flea market.
