I remember the nurse using a round thing on her thumb with little points that they gave it to you with. My scar was small but my granddad's was big & nasty because they cut you with a knife so when it came time for my mom to get one he made her get it on her behind so she wouldn't have a scar. She' is 74 and my grandad would be 109 if he were still around. My how things have changed.
