I’m looking for a copy of “Four Methods of Tying the Hackamore Diamond Knot; plus the Knot in a bottle” by Eugene Ulrich. Any info on actually tying this knot in a bottle is appreciated. I found a picture of this bottled knot in a pamphlet on Braider Journal. An online search didn’t turn up anything.

A Reddit thread on the topic, they mention

IGKT NAB has become IGKT NA, but the InterKnot archive doesn’t seem to have gone with.
