additional 'flume' refinements

So apparently polishing and v-cuts are very expensive.  Yet a straight cut simply honed costs much less (still not cheap, but not a budget-buster).

Given this, I begin to explore ways to arrange a series of flat-cut stones in an alternating line (like a 'stone zipper') that appears like a v-cut only as viewed from either end of the piece.

Through exact alignment and a consistent angle of cut, a discontinuous flume-like channel becomes apparent.  Each angled stone cut offers pairings of informal seating.  

Add a few well-chosen small fossils as hidden surprise elements...
