The Alpine Butterfly Knot

There are lots of different techniques and lots of different YouTube videos about them, but today I found the method I liked the best:

Climbing instructor taught me very similar technique that seems to give neater tie – before finger grab, move one edge to middle then grab edge cord with finger.

This was also a knot that I had only been vaguely familiar with.

I think there’s also a way of tying it one-handed. Perhaps an extension of the one you demonstrated?
