When I first started quilting my youngest son wanted to help. Of course being a boy he wanted to use the rotary cutter. So I held the ruler as far back as I could and he cut, he cut right over the top of my nail on my middle finger. I instantly brought my hand back and covered it with my other hand so it wouldn't bleed on the fabric and so he couldn't see it. He was around 12 or 13. His eyes were the size of dinner plates and so were mine, he threw the rotary cutter on the floor and followed me to the bathroom asking if he'd cut off my finger. I was afraid to look, afraid to let go of my finger. Turning on the water with my white knuckles letting the water get really cold to help stop any bleeding that may be under my white knuckled grip. As soon as I let go the blood just poured out, I'm cut on the diaginal from nail tip to knuckle, making it look much worse than what it was, my son freaks out, thinking I'm in need of a medic. Being a tough single mom and seeing that I'm gonna loose this nail and doubting it even leaves a scar I tell him to get the large bandaids and some gauze. After bandaging it up and applying ice, and holding my finger over my head I got the bleeding to stop. My finger is good as new, and my son hasn't wanted to help ever again. I lost the nail, it grew back, no permanent damage. Do I use a safety glove now, heck no.
