And yes, when written like that it's a bit hard to visualize but if you tie your shoe with "two passes around the first loop" in mind, it's a pretty natural motion.
Simply tie the 'bunny knot' the other way (start with a loop on the left instead of right), apparently.
Until you realize it totally depends on how you made the initial 'twist laces together' loop.
It's not easy to see from the video, but he's doing left-over-right, and so a right-loop for the main bow is of course wrong.
If you make the initial twist right-over-left and then under-and-through (as I learned), then you can tie the bow starting with the right loop, and the resulting knot does not twist vertical when tensioned, and does not come undone easily.
So yes, some people have been doing it wrong, but it's easier to fix the initial twist loop than the main bow loop imho.
Ian's knot looks even more secure though.
I think they're the same, but the method is now purely muscle memory for me and the diagrams on Ian's page don't look familiar.
Edit: Looking around Ian's site, they are different. The method I (and also Matt Parker) use is the "Ian Knot": https://www.fieggen.com/shoelace/ianknot.htm
What's wrong with you people!!!! That's why your laces keep coming undone!!! The trefoil should be right-over-left.
lol
But it does look magical, I'll have to try it, switching the forward/backward loops due to my right-over-left trefoil.
They have to match. From all the "you're doing it wrong" posts and videos I can only assume that everyone (else) is learning left-over-right for the initial twist, and then right-loop for the main bow, which of course slips.
A few years later I took up partner dancing and I'm glad that losing a lace in the middle of a dance is a rare occurrence for me - it's super annoying on the rare occasions that it happens (either interrupting the dance to re-tie or putting up with the lace getting underfoot for the rest of it)
PS am also middle-aged...
Then I found what it actually is, it's a doubly slipped square knot, a square knot is right over left and left over right, and slipped versions are usually just finishing with a loop that goes back the way it came, so I can figure it out from the much easier to memorize verbal description.
"Ian's knot" is just the regular shoelace, done wrong - starting with a left-over-right twist, instead of right-over-left. So that knot will twist to vertical and self-loosen.
