I´ve had an idea for a while!
Since october is breast awarness mounth why don´t everybody knit their own pink scarf in september to wear through october. You can use any yarn and any pattern as long as it´s pink. I even started some kind of discussion on Ravelry about it, since I havn´t done much there I´m not sure I did iy on the proper place.
Wearing your own pink scarf will of course not stop you from buying the pink ribbon or donate money in another way for research!
