3 concrete sheets of 4ft.*2.6.ft*0.5in. made of Craters Concrete.  GREY WAVY crawls, topples and takes off to escape from the workshop.    This 66 pound concrete sheet is perfectly smooth.  However, on the reverse side, a landscape of craters exists

WHITE WAVY


concrete sheet of 4ft.*2.6.ft*0.5in. made of White Craters Concrete on metal feet

This white sheet which seems so flexible and light is made of concrete.
A side is perfectly smooth and soft,
the other one damaged by unique craters and blur of grey.

Apparently overhanging on its non-vertical feet,
this WHITE WAVY seems to slide and about to fall,
nevertheless it is very steady!
