I sew barefoot, a few years ago I was making a quilt top for a niece. I hate to quit until I'm done, almost finished and scooted my left foot back, felt a sting. Checked and only saw a drop of blood. Finished the top and cleaned up before checking my foot. Found a piece of a needle in the floor. The other half was broke off in my heel. Went to the er and the xray showed a 3/4' piece in the foot. The odd thing was that the xray tech said I was the 5th person to come in that day with a needle stuck in the foot.
