I found the tutorial on Bits and Spurs.
Misty Owl gladly accepted the first halter.
I did not get the knots even on both sides, but it turns out a lot better then others I have tried.
Fun fact: Misty got her name because her mold is Misty’s Twilight and there is an owl in Guardian’s of Ga’hool named Misty. So there forth Misty Owl.
