Start
off with the basic pattern and construct within this pattern an
equilateral triangle as shown in the diagram.








Now construct a circle with
its centre in the middle of pattern and its circumference going through
the indicated intersection points.








Construct a circle with its
centre in the middle of the pattern and its circumference just touching
the bigger triangle.








Now construct three circles of
the same size as the previous one, but with their centres on the indicated
intersection points.








Three more circles have to be
added to finish the reconstruction. They all have their centre at the
middle of the pattern. The first circle just touches the three previous
constructed circles. The second one just encloses the big triangle and the
third circle just fits in the small triangle.








The only thing left to do is
picking the right objects or in other words: rubbing out the appropriate
lines.








The places where the crop was
flattened we colour black. The places where the crop was still standing is
left white.
