My Uncle Bill- whose initials are also WD- recently asked my mother to mend these socks. He loves them and wears them when he hunts in the Fall. They are not worn out and in need of darning- there are just a few loose edges and stitches. They are in remarkable shape for 50+ year old socks. I will carefully mend them as well as I can and send them back to Uncle Bill. They will keep his feet warm many more hunting seasons.
Maybe we can even keep them going for another generation or so- Uncle Bill has a son who has big feet and the same initials who like to hunt in the Fall.
