You can actually create an interesting centerpiece by using whatever small collectibles are around your house. The key is to find a common theme or element to pull things together. In this particular setting, the common elements are the Oriental theme and blue color of the pottery.
As in all centerpieces:
Keep the balance in height and distance among the objects.
Make sure the items don’t
Mixing other Oriental elements you have around the house, like figurines, will complement the blue and white ceramics.
