熊谷/Kumagai
“熊谷/Kumagai” is one model of 49 kinds of “連鶴/Renzuru”.
Renzuru means connected-cranes which are made of only one paper without glue and tape.
49 kinds of Renzuru was in the book which is “秘伝千羽鶴折形/Hiden-Senbazuru-Orikata”.
The book was published in 1797.

Kumagai is the model that three cranes are connected to each other with wings.
Connecting parts are long.
Therefore, it is easy to make this model!

Preparation of an origami paper
【Size】
a 17.5×17.5cm paper or it is bigger than 17.5cm.
【Kinds】
・Basic origami paper
・Double sided origami paper
・Washi paper
I made this model with a 17.5×17.5cm basic origami paper.
Since connecting parts are long,
it is easy to make this model with a basic origami paper even.

Fold the paper in half.

After making a crease, cut the paper on the blue line.

Then fold the paper in half vertically and in four horizontally.

After making creases, it looks like this picture.
Preparing an origami paper is completed!
Make creases
To make creases on a paper before cutting the paper is very important.
If you cut a paper first before making creases, it will get harder to make creases on the paper.
Also, there’s a possibility that the paper is cut halfway when making creases.
This step is making basic-creases on each square.
On the other page, there is how to make basic-creases.
I will paste the link down below.

Make basic-creases, which are the green lines and the blue lines in this picture, on each square in the paper.

Make basic-creases in each yellow square.

This picture is taken after making basic-creases in each yellow square.
Please make sure whether there are the creases, which are the green lines and the blue lines in the 2 pictures ago, in each yellow square.
Cut a paper
Cut your paper after making creases!

Cut the paper while referencing the diagram.

This is an enlarged picture.
Cut the paper until half of a small square.
Make sure the direction of each crane
When making Renzuru, to fold cranes while making sure the direction of each crane is very important.
On this site, I will draw lines on each square in a picture.
Make cranes so that the lines are changed to wings.
I recommend that you draw lines lightly on the back in order not to make a mistake.

Make cranes so that the yellow lines are changed to wings.
After making sure the direction of each crane, make the model – Kumagai.
In the next page, there is how to make the model.
If you try to make it by yourself, I recommend that you don’t look at the next page!
