That is just ludicrous! I was given sideways looks when I brought a plastic crochet hook. People wanted to know "how I did that". I said, I put it in the bottom fold of my purse so it looked like a stay in the purse or like a part of the purse. Plastic hooks can certainly do damage and are made not to break easily, so why not a sewing needle. Will be interesting to see if your experiment works. Keep us posted.
