I sat on a needle a couple weeks ago. Luckily, it had about 5 inches of thread on it. It was a darning needle. It was such that I had to have DH pull it out. Had it not been for the thread, I would have had to go to the ER to remove it. I sat then scooted just that quick. I did have a dr appointment the next day and got a tetanus shot. The thread was the same color as the cushion on my chair.
