MAKE A FIBONACCI FILTER
Don’t believe us when we say that Fibonacci’s sequence is everywhere in art, architecture and nature?
Well, why not see for yourself? This interesting little invention is a challenge to make but you’ll soon
be finding Fibonacci all over the place. Why not take this along next time you visit an art gallery? Just
don’t forget to send us pictures of you hunting down the Golden Ratio with your Fibonacci filter!

MAKING THE FILTER
1
Take a piece
of squared
paper and,
using a pencil
and a ruler,
very carefully
draw a
Fibonacci spiral following the
instructions on pages 10-11.
Thread another
split pin through the
hole in the top left
corner of the front
cover, through the
frame and out
through the back cover (see blue
arrows), binding them all together. Use a
loom band to hold your filter closed.

Taadaa! You can use the Fibonacci Fun
times Filter to improve the composition
of your drawings –
here’s a quick sketch I
did using mine as a
guide.
2
Place a sheet of plastic from your
AQUILA wrapper over the Fibonacci
spiral and
carefully trace
it onto the
plastic with a
permanent
marker.
3 Spread glue on the backs of both
frame pieces and stick the plastic
between them, being careful to line it
up so the spiral
sits squarely
inside the
frame. Leave it
to dry
completely.
When it is
totally dry, trim off the excess plastic.
