It is actually not okay for the shapes in a tessellation to
overlap to cover up any gaps or to overlap for any other reason whatsoever because,
by definition, a tessellation is comprised of shapes that make up a pattern
that are so perfectly arranged that no gaps could possibly exist. If any gaps existed, then naturally, the
design could not possibly be a tessellation.
A good example of a tessellation
is the pattern of a soccer ball.
