I'm with the others. Don't cut it. Raffle, sell or auction it off whole instead. It would be a terrible waste to cut it up.
Thank you and your church for the help you're giving to cancer patients. I am currently fighting stage 4 melanoma and can tell you from personal experience you are making a huge difference for the people you're helping. While I was in the hospital last December I received a gift bag from Pacific NorthWest Needle Arts Guild. It meant a lot to me that people I didn't even know cared enough to give their time to make gifts like that. I wear the hat that was in the bag pretty much every day.
