Does anyone know where the last piece of the vase in Winhill is?

First piece is there in the mansion before you leave.
Second piece is near the white flower in the house where the old woman is standing outside.
Third piece can be gotten from the chicobo at the chocobo crossing.

The final piece is a little difficult....in the house where Raine lived, talk to the old woman until she mentions the aroma of the flowers downstairs. Then go down and inspect them until a "ghost" of Raine shows up and turns into a cat. Investigate the cat, that is where the final one is.

I don't which piece your talking about so I will answer all of them.

First piece is the man in armor in the mansion. talk to it and you will find the first piece.

Second piece is in the flower store in the middle of the town.obsereve the white flowers and answer yes when the old lady asks a question. then you will find the second one

Third on go down from the flower shop and you will see a chicobo. try to talk to it as it runs by and it fly to the air dropping the piece. you can talk to it again to get some rare items.

Third piece go to raines house and talk to the old lady upstairs. talk o her unil she says about the fragrance of some flowers. go down the stairs and inspect the flowers on the table to the far right. then you will see raines ghost. talk to it and it will turn into a cat. talk to the cat and you will find the last piece.

Then talk to the owner of the wase and he will give you a gift.
