Correction: A check shows I do not use the Berluti knot. I use this one:
Ian's Shoelace Site – Ian's Secure Shoelace Knot
This is the Berlugi knot:
Ian's Shoelace Site – Berluti Shoelace Knot
Ian's Shoelace Site – Ian's Secure Shoelace Knot
This is the Berlugi knot:
Ian's Shoelace Site – Berluti Shoelace Knot
