Diabetic Retinopathy Treatment Care

So, I wanted to start collecting money as donations for the Juvenile Diabetes fund, but I also wanted to be able to give the people who donate a little something. I also think that that would attract more people to donating. For example, when I collected money for the Breast Cancer fund, I gave out little pink Breast Cancer ribbons to each person that donated. I wanted to do something a little different for diabetes though. So, does anyone have an idea?
