1. Wore an HY tie to class today and a student liked it so much she decided she was going to buy one for her father's birthday.
2. The back seam shows through in the knot. Is this avoidable at all (I don't think I'm tightening it too much). Perhaps a different knot than half-windsor?
I would go with a four in hand here--that knot is a little big tied in a half-windsor.
