The one single overhand knot is not as convoluted a knot as it should, to serve as a "neck" for a secure noose-hitch. So, it is tempting to try two overhand knots instead (
"When one is not enough, try two", said one of the discoverers of the double DNA helix ...
). The Blimp knot is nothing but such a two-interlinked-overhand-knots compound knot.
See the attached pictures for another noose-hitch based upon a two-interlinked-overhand-knots neck. Shown are a "correct" and a wrong version . The wrong one, suffers from the danger the tail will be untucked and untied, if the upper overhand knot is not tightened adequately - and will not remain in this state ever since. That is the reason it might serve as a knot for a midlne bend, but not as a neck around the tensioned standing part of a noose-hitch.
However, I think that the purpose of this thread was a noose-hitch which will be tightened when pressed hard on the surface of the wrapped object, by the compression forces the surface of the object imposes on a nub of as simple as possible a knot...It seems that such a knot should drive the tail towards the surface of the object, so the interaction of the tail with the surface will secure it further.
