Apart from squares , rectangles and hexagons are most commonly used
in origami. If you are keen
on folding flowers , then hexagons
would always be the choice. There have already been a number
of methods
regarding how to cut regular hexagons. However , they
almost invariably involve
folding the paper in multiple layers , which
would result in inaccuracy. The following method was
devised by me just about a year ago when I felt the urge to get a quick and
easy way of cutting a
true regular hexagon in order to fold the
flowers requiring a hexagon to start. Although this method
is very fast and easy , by which a true hexagon can be produced within a
minute , its accuracy is
absolutely stunning , which I believe it's a record. In addition , there's no need to start with a true
square with this cutting method. Only an approximate square will do.
A) Tools
Basically
, they are the same as used by those in making a true square
as described before.
However , this time the
one really in need is the 30° / 60° set square, more
exactly the 60°
angle. As hexagons are mainly used in folding
flowers, boxes and stars , they are usually
made from those
ready-made origami papers with side length 15 cm or less.
So we have
to use another set of tools of smaller size. The
30° / 60° set square I'm using is about 14 cm
on the
slanted side while the steel ruler is 20cm in length. In addition
, we can use this set of
tools to correct those ready-
made origami papers which are not true regular squares.
With
this method , we can start from paper of any size . We only need an approximate square to
start with. It won't affect the overall accuracy of the end product.However , for the sake
of simplicity , we start with a ready-made true square.

B) Procedures
1/
First , fold the square in half , bringing the upper side to
the lower. Crease firmly and then
turn the paper anti-clockwise
about 30° as shown in the photo. This only aims to facilitate
cutting in a comfortable way.
|
c)
2/
Place the slanted edge of the 45° set square against the
slanted edge of the paper's
with its tip about 3cm away from
the right to corner of the paper. Then place the
slanted edge
of the 30° / 60° set square against the 45° set
square's with
the 60° angle facing upward. The 60° tip should be
a little bit beyond the 45° tip.
|
3/ Place the steel ruler against
the vertical edge of the 30° / 60° set square. When
true close contact is assured , cut away the paper on the right side of the ruler. A
true 60°
corner is then formed. Then turn the left side of the paper
over to the
same position as before and repeat the previous procedures.
|
g)
4/ When finished , open the paper. You will see a diagonal sloping
downward
from right to left. On both sides of the right
top end point of the diagonal are two
previously cut edges.
Now turn the edge on the right side of the end point
anticlockwise
to a horizontal position as shown in the photo. Now the
diagonal is seen sloping downward from left to right.
|
5/
The upper edge and lower edge joined by the diagonal are parallel
to
each other. Now bring the lower edge to align
with the upper edge as shown.
This is the most crucial step
governing the overall accuracy. With a little bit of
patience
and
care , this can achieved easily and accurately. Or you may use
the
straight edge of the set square to help.
Then , crease firmly.
|
6/ Now you will see the lower layer
of the paper protruding from the upper
layer on the right
side of the paper. Then turn
the right edge into a vertical position
and place the slanted
edge of the 45° set square against the edge of the upper
layer.
Hold it firm with your right hand. Then place the steel ruler
against the slanted
edge of the 45° set square. Finally
,
remove the set square and cut off the extra
lower layer as
shown.
|
7/
Now turn the left portion of the paper over to the same position
as before.
Repeat the previous procedures. Afterwards ,
open the cut paper and a
beautiful true regular hexagon is obtained.
|
Note
: To test if the hexagon so formed is a true regular
hexagon
, you can fold along the axes of symmetry.
Actually these crease
lines are also needed as a rule.
If the upper layer and lower
layer overlap each other
completely in all cases , then it proves
itself a true
regular hexagon.
