I just wanted to add, the colors and the ribbons are not about celebrating the cancer, they are about fighting and defeating it!
Those who embrace the ribbons and colors are embracing the battle against that disease, and see them later on as symbols of their victory, not reminders of their illness. I have many requests for my ribbon pattern quilts and am always happy to make them. When I get a request from a family member for a ribbon quilt, I always make sure that they know this is what the recipient would want. In almost every case, they are sure and the quilt is well received.
