I'm a six-month survivor. I'd be honored to have a friend make me a pin like that ... honored to have a friend that cared so much about me that she would do something like that! I'm sure she'll love it.
My cancer is rare and doesn't have a color ribbon, so a friend of mine designed one. We even have car magnets! And I adopted the design into the logo for my nonprofit organization, Fighting Cancer, Inc. I'm going to try to post the pic. I bet it would be a fun ribbon to try to do into a quilt ... hmm, I feel a project coming on :)
