in your precursors, there are no pointy stones, and depending on the stone shape, we leave many in the quarry or supplier. Or, separate them so that they are not used for the incorrect uses - determined by the pathway atmosphere we are trying to achieve.
all I wished to suggest was that the shape of a stone indicates what type of setting the stone would be used in. Stones with points, any points are not in the pathways you have indicated... stone: pointy stone/angled stone/one straight line on the stone, these appear as signposts, and a pathway should be readable such as -> <--- or / or | or a \ or 0 or 0
.. all are lines of force or pressure that indicate what the walker should do on a subconscious basis, so that they only 'respond'.
the worst examples I see of walkway step stones are long stones going sideways across the path for 'ease of walking' or something akin to that notion... when it really means stopstopstop...
think of the highway and a passing lane. we understand solid line to mean do not pass, and the dotted line to mean 'passing at high speed'.
Now compare the 'safety crosswalk' with lines across the walkway ->||||||||||||| ->
and - firstly this is a dotted line saying 'go fast and pass here' to traffic in line with the 'line of force' and to the pedestrian this means !STOP! !STOP! !STOP! at every line encountered.
we tell people- kids to not step over the line figuratively and in reality, at trains, in banks, in 'line-ups', at sidewalks.... crossing the line is having gone to far.. then why create 'lines to cross'... this is fundamental in why gardens work or do not work.
a pathway, as I'm sure you know and mentioned here and above for the conversational insight, is a narrative, such that a pathway to the beach is really a pathway that leads from
the sea, the sailor coming ashore -> onto the land, and the staggered placement is really the sailor getting his 'land-legs', or another description given when I foolishly asked, "what kind of path?", was '(shrug) make it like a drunken sailor'.
[while I was still a lippy lad, I muttered " drunk to the sea or from the sea?
? "- he heard the mutter and commented quite smugly... "now you to use head.. how stone using.."][ps.. he had me take it apart 4 times and i rebuilt it 5 times and the last time was the same as the second time.. shall we say the exercise was not lost on me.]
(:. Enough lip from me, I leave selection and striking of stone to your good taste...)
