I never did that . . . but I did do something much dumber. I had put my fabric in to start sewing and it bunched up under the needle. I stuck my fingers under there to pull it out and forgot to take my foot off the pedal. You guessed it!! I put the sewing machine needle straight through the top of my fingernail, clear all the way through my finger and the needle and thread came out the other side. Of course I was home alone and freaked out. I had to yank the thread out of my finger and it hurt like heck. My finger was sore for weeks. We all just need to be careful. I have been sewing 30 years and had never done that before. But I got careless and got hurt.
