I've been quilting since 1980, but 9-10 years ago -- when I should've known better -- I cut off a tiny bit of the tip of my right index finger. It bled like crazy. It happened on a Sunday night, so I was probably too tired to cut & too stubborn to stop. It was difficult to stop the bleeding, but hubby kept saying, ah, you're fine, so I sucked it up & went to bed. The next morning, I took off the wrappings & it started bleeding again. I went to work like that & my supervisor (I work in home health care), who is a nurse, sent me to the ER.
Now I like to think I am smart enough not to use sharp instruments when I'm tired.
