I had a lady in one of my classes early on (right after rotary cutters came out) she nicked her finger but didn't say anything, just put her hand under the table, by the time I found out about it, she had a puddle on the floor. Got the first aid kit and bandaged her up, then had to clean up the mess. Ah we live and learn. Ever since that I stress. "Make sure you know where your fingers are before you cut!" Was at the LQS yesterday and a lady was purchasing a kit to do (her first quilt) Was asked about rotary cutters etc, so told her what I use and why and also "be sure you know where your fingers are. Hope she heard me. But she is a nurse, so would know what to do if she does cut her fingers.
