HELP! Because I'm the big Halloween lover at work, I've been chosen to do our pumpkin for the hospital's contest. They want it related to our field which is dialysis. I'm no pumpkin carver, so I was hoping to decorate it instead of have to carve it. Any ideas? Dialysis is where we take the blood from patients, run it in tubes through a machine, clean it and send it back to the patient.
