What is the Origami Frog?
... ... |
The Origami frog is a folding from a sheet of paper with
the aspect ratio of 1:2. |
What makes this frog special
is you can make him jump. Press the rear part and let it suddenly go.
This is also a reason that it is well received by children.
... |
|
It is also called jumping
frog,
hopping frog or
Japanese Frog.
Folding the
Origami Frog top
1
... ... |
Take a sheet of paper of the size A4 (8 1/2" x 11").
Paper used for ink jet printers will do.
Fold the upper half down on the red line.
 |
Red means a valley folding, blue a mountain folding on
this page. |
|
2
... ...... |
Cut off the lower strip. |
3
... ... |
The result is a square. |
4
... ... |
Find the centre line by folding the left side on the
right side and by unfolding.
Cut off the right side. |
5
... ... |
You will now work with the left side only.
The paper forms two squares one upon the other.
I have drawn a line to make this clear. |
6
... ... |
Fold one of the squares into diagonals and unfold it. |
7
... ... |
Fold the upper rectangle backward on the blue line and
unfold it.
Lay the triangles at the top and at the bottom on top
of each other.
Push the triangles on the right and left inwards at the
same time, so that the blue lines touch. |
The following drawings are
twice as big as the previous ones.
8
... ... |
The result is the flier triangle from the Paper
Pigeon.
The next step is already included:
Fold the lower portion up on the red line. |
9
... ... |
It must look like this.
The next step is already included:
Gently lifting the side of the triangle, fold the edge
to the center as shown by the red line.
Repeat on other side. |
10
... ... |
It must look like this. |
11
... ... |
Fold the lower corners backwards and unfold them. |
12
... ......... |
Fold the upper rectangle upwards on the red line and
keep it upright. |
13
... ... |
It must look like this.
The next step is already included. It is a little bit
awkward.
Fold both green triangles on the red lines upwards to
the left and to the right.
Put the upright, with the triangles connected, in the
drawing hidden squares outwards at the same time. A "boat" is coming out.
The upper border of the boat is coloured green in the next drawing. |
If you don't understand this step, please go to Klaus Gresbrand's
video. (URL below).

|
|
It must look like this. |
15
.... |
Lay the front edge of the "boat" upon the rear edge.
The next step is already included:
Fold the right and the left triangles downwards. |
16
... ... |
It must look like this. |
17
... ......... |
Fold on the red lines upwards for the four legs of the
frog.
Beware that the tops overlap a little. |
18
|
|
The frog is finished. |
If you unfold the frog, you get a symmetric
pattern.
Variants top
Obviously the frog of two squares described on this page
is a classical Japanese folding.
For example it is described on the German page labbe.de
(URL below).
I recommend the video on Klaus Gresbrand's site (URL
below).
It has numerous variants.
1
I left out the last steps of the just mentioned two descriptions.
... ... |
... ... |
By making a valley and a mountain folding, the frog
will get a stair effect.
Thus the frog is shorter and more a toad. |
2
Besides it is normal to leave out step 4 of my description.
If you use double layers, the paper is stiffer and the frog can jump better
later on. But then there is the handicap that folding the legs needs more
efforts, which my test person (aged 7) didn't have.

... ... |
This is quite another frog, which is introduced on the
German page basteln.machtspass.com made by I. Schwarz.
You start with a square and the flier triangle.
What makes this frog special is it has eyes. |

on this page - and to more frogs.
