\centerline{{\largebx Papercut Patterns}}

The technical drawings in this document can be used for creating 
papercut or works of art of a similar nature.  They are meant for patterns
with multiple lines of symmetry, such as papercuts made by folding and cutting
patterns into two or more layers of the paper.

Half of the drawings contain a circle divided into sections by two polygons,
$p_1$ and $p_2$, where $p_2$ has twice as many sides as $p_1$.
Put another way, the lines of $p_2$ divide each triangular section of $p_1$
into halves.  

The other half of the drawings contains one or more separate sections from the
``polygon-circle'' on the previous page.  These sections can be used for
creating patterns, which can then be transferred to the drawing with the entire
``polygon-circle''.  The dashed grey lines can be used for aligning them with
the corresponding lines on the drawing of the polygon-circle.

%% !! START HERE:  I need to add more sections and arrange them on the page.
%% LDF 2011.01.02.
More than one section can fit on a single page, but it requires some fiddling
to get this right.  As of this date (January 5, 2011), the author has only
done this for the 5-gon/10-gon, 7-gon/14-gon and 9-gon/18-gon sections.
