I did that one time too. The needle went rignt through my finger nail and out the other side. I was home alone so I knew I could not panic. I actually had to get the needle out of the machine before I could remove it from my finger. And the I had to go to the garage and get a pair of plyer to pull it out. I never had any blood or pain. There certainly is alot of force behind my Viking Designer machine. But I love it. It is truly my best friend during the cold snowy winters here is Iowa.
