I was talking w/ a jewelry sales person the other day and he
mentioned a client who came in to have her pearls restrung. Very
nice pearls and she knew it. She insisted that they be double
knotted. When the sales person said that one knot should be fine,
she held her ground and insisted that she wanted DOUBLE knotting--
one knot on each side of the pearl..
Got a nice chuckle out of that.
