Ahh I just did this a week ago! I had my laptop next to me on the desk and my sister sent me a message on IM. While I was quilting a quilt for charity also, I looked over to read while sewing and BAM the needle went right through my fingernail and through to the other side. It reminded me of one of those headbands for halloween that look like you have a knife through your head. The needle broke off the machine and the thread went through my finger also! I cut off the thread that was attached to the machine and pulled the top piece out, but the bottom piece wouldn't come out. Since I was in my craft room, my DH grabbed my jewelery pliers and we finally got the bottom piece out with a piece of now red thread attached. My oldest son had the phone ready to call 911 and another son (who is terrified of blood) was shaking so badly. All in all, it left a mark under my nail but the pain is very minimal. Glad I am not the only one that has done that!
