I've blogged on this knot before, as the Chinese Crown Knot. I bring it back up since it's one of the knots shown in Decorative Fusion Knots by JD of Tying It All Together. It's one of those knots that works well for a lanyard/fob/bracelet, when tied in a series, and a longer length of them has the look of a chain.
The knots have a square pattern on one side and a cross pattern on the other, which I think goes well with the Victorinox and Wenger Swiss cross shields.
I used about 6 feet of 2.4mm braided nylon cord to make this lanyard with a finished length of around 1.5 feet, adding a snap hook. I started from the center of the length of cord and made each knot about 3/4" to 1" apart, just doing it by eye instead of using a ruler. I finished by wrapping both ends around a swivel snap hook, loosely tying a lanyard knot, pulling the whole length of the lanyard through the center of the lanyard knot, then tightened it up to finish, trimmed and tucked the ends.

And shown done with two different types/sizes/colors of cord with the knot doubled, and used with paracord for a wallet chain/lanyard.
