I liked the ideas that we had last year. I don't think enough people will hear about this to make it work, although it'll be incredibly epic if one of us meets another AW because of it, just out of chance (you never know. I usually don't talk to random people in public, but I did once in the WWoHP, to compliment a girl on her Hogwarts uniform, and it sparked a conversation and we found out that she lived in the town next to mine! It's a small world, guys, so you never know XD)
I... honestly have nothing new to suggest. So this post was sort of random. Anywho. Bracelets, pins, anything with "AW" on it would probably be cool.
I know that I'm going to my town's midnight premiere as a Gryffindor, just because it was super easy. I have a Gryffindor robe from when I was, like, seven or eight, and all I had to do was buy a cheap red tie and paint gold stripes on it. So I could probably stick an "AW" somewhere on there.
