I would love to see the Pi Pendant made into a window cling/magnetic bumpersticker...I think it would look great and be a great way for sisters to easily recognize each other when on the road!
As an alum, sometimes I felt like a collegian when I had my letters on my car (I got a new car so my window sticker is gone
)...this would be a way where I could still let sisters know I'm an ADPi while keeping my vehicle from looking like I'm still in college!
