At the Pride NW festival I went to in Portland, there was a booth for a trans site/center or something that was donating binders right there on the spot; you could drop them off or pick them up, depending on how far you were into transition. I'm stuck between deciding whether I just want to offer my binders to people on my transition blog, or just sending them to the nearest binder donation thing to me. Decisions, decisions...
EDIT: Just realised that "In a bind" donations was a specific org. Sorry I can't help, I don't know anything about them, but maybe someone here does. I would be more inclined, if you're unsure, to maybe ask around Susans for kids in need?
