Been there, done that on my long arm quilting machine! Those machines have rather large needles too. Last summer, I was working on a customer quilt and in a hurry, sewed through my pointer fingernail in 2 places. An x-ray at the ER (on a Sunday night) showed no broken bones. It really didn't hurt much and my finger didn't bleed much or on the quilt either. It took about 2 months for all the feeling to come back in my fingertip. Right after everything was back to normal, I sliced off the side of the SAME finger with the rotary cutter. Thankfully, it healed just fine and I have finally learned to slow down!!!
