I had thought maybe it was Delft--but it's not. The Chinese porcelein (sorry about that typo in the subject heading!!) comes closest so far in that there's a lot of white showing, unlike Willow that has a great deal of dark or navy blue.

If you took the shot on the Bill's URL, and made the design look more western than eastern, it would be the type I'm looking for---oh, gosh, if it turned out to be French, that would be ideal, perfect!

Thanks so much for the suggestions,
Theresa
