I started using a taught line hitch with cotton cord for hanging pictures.
The taut line hitch makes it easy to adjust the height without moving the nail and the cotton cord helps keep the taut line hitch from slipping (vs says monofilament).

The taughtline hitch is a much better knot for this.
I never could master the trucker's hitch[1] though :-)

L over R, L over R would make a granny knot.
But maybe in the UK both are called a granny knot?
Interestingly, when a granny knot is collapsed (the cord on one side gets pulled taut), it becomes two half hitches. When a square knot is collapsed, it becomes a larks head or cow hitch knot. In the balanced state, the granny is a weaker knot and the square is stronger. In the collapsed state (then cleaned up a little bit), two half hitches is a stronger knot than a cow hitch.
Same in the UK.
Also, it's a taut-line hitch:

taut, meaning tight, not taught, the past tense of teach.
It's essentially a quick release Prussik tied with the working end.
You can use a toggle, or slip a second bight through the first to prevent accidental untying.
Big benefit is that it is faster to tie in longer lengths of cord and it's faster to undo, being quick release.
