This is basically a kind of cross-section of the farthingale with extra
lines. Your diagram should be acurately scaled down, 1mm to 1cm so
that your final measurements are accurate as well. This is how to
1. Work out the diameter of the waist
(assuming it's a perfect circle). This is
the top line (scaled down 1 mm to
1cm). The equation for this is:
circumference / Pi (3.14) = diameter
your waist-ground measurement
up the shape with lines from the
ends of the waist diameter line to the
ends of the stride measurement line.
up the waist-ground line and
these lines and you have the
exact diameter of each hoop.
7. From this figure, you can work out the
circumference using geometry (3.14
(Pi) x diameter).
I hope this makes sense...?
