The orphanage has a bank account where donations can be transferred to:
Krung Thai Bank (Mittrapap Rd. Branch)
Nakhon Ratchasima
Account No.: 306-1-13904-4
Account Name: "Thailand Children's Home"
That is, if you trust people acting for charities. Some are honest, others aren't. Best is, if you are in close contact with the charity and do supply them directly with the goods they need or lend them a hand. I do hope we get some more info about this cause and how people can help who don't trust collectors or employees of charities.
