I saw a photo of a necktie tied in an Eldridge Knot a few months ago [link updated]. It looks so intriguing, but I hadn't had a chance to try it until Christmas day.
On Christmas I conscripted my older son, David Ricardo Palmer, and we used a necktie given to me for Christmas a year ago by my daughter, Joan Robinson Palmer, to try it.
It is a very unusual knot. My granddaughters love it, and so I may try it a few more times.
