I learned a painful lesson....PAY ATTENTION WHEN USING THE SEWING MACHINE!!!!. I looked away to glance at the TV and sewed right through my finger. So there I was, stuck to the machine and hurting somethin' awful. The only way I could get free was to backstitch. I still had the thread going through the nail and out the other side of my finger. So I pulled it out, then it started bleeding. Thank God it did not hit the bone or I would have needed help it get free. At least it was a clean wound. Now it is just numb, after two days.
