For pledging the pin/necklace changes each pledge period. Like when I pledged, we didn't have a pin, we had a gawd-awful giant wooden heart that was badly painted that we had to wear. This pledge period we had the girls have a small necklace w/a miniture rose attached to it. They also have to wear a small handmade pin made out of foam hearts w/their name, semester, and the letters on it.
Once active, we don't have anything
We still need to find a pin maker.
