Leukimia ribbon product

[Michiganmickey]

My friend was diagnosed with Leukemia in early August and I am doing a fundraiser for his family at my school. We were are thinking of doing a hat day where kids pay $1 to wear a hat in school for the day. But to make sure they paid we usually give them something to wear or something. Usually its like a piece of yarn on your wrist but since I'm trying to raise awareness for leukemia I was wondering if there was maybe a sticker, stamp, or temporary tattoo that maybe has the leukemia ribbon. Any one have any ideas?? Its a school with almost 800 kids so it would have to be mass product but cheaper too since it would come out of my pocket. It doesn't necessarily have to be the ribbon. Thanks!! °o°
