I emailed ST. Jude's Children Research Hospital and asked if they accept hats and bandanas donations for their patients who lost their hair because of illness. They said they do.
I did request for them to take pics of the donation either with patients, or maybe with just a couple of staff, to show our donators and out hard working volunteers that the donations arrive there. But they said that they can't do that :(. I'm a bit dissapointed because I've been so loyal to them, I'm a monthly donator of their hospital. I just don't understand why they can't do it.
