The diagram of Mitsugaichi

Make this model while folding a paper on the dotted lines.

Preparation of an origami paper

Recommendation

【Size】
a 17.5×17.5cm paper or it is bigger than 17.5cm.

【Kinds】
・Basic origami paper
・Double sided origami paper
・Washi paper


Fold the paper in half in each direction.

After making creases, cut the paper on the blue line.

Cut the paper like this picture.

Then make creases at the dotted lines.

Also, make creases at the dotted lines.

Next steps are making creases at the dotted lines.

When making a horizontal crease,
fold the bottom to the green line that you have made.

Fold the paper like this picture.

When making a vertical crease,
fold the left to the center line.

Fold the paper like this picture.

Make another horizontal crease and another vertical crease as well.

After making four creases, it looks like this picture.

Preparing an origami paper is completed!

Make creases

In the “A” square, make basic-creases.

In the “B” squares, make inside-blintz-crane-creases.

In the “A” square, make basic-creases which are the green lines and the blue lines in this picture.

In the “B” squares, make inside-blintz-crane-creases which are the green lines and the blue lines in this picture.

When making inside-blintz-crane-creases on big squares,
a small square end up being made some creases too.
The creases are which you don’t use when folding the small square.

It is better not to make creases, which will not be used, as much as possible.
Because it get harder to fold the small crane.

Therefore, try not to make creases on the part which is painted blue when making inside-blintz-crane-creases on the right square.

When making inside-blintz-crane-creases on the right square,
making the creases without making creases on the part which is painted blue.

On the other side, making the creases without making creases on the part which is painted blue as well.

When making inside-blintz-crane-creases on the left square, make the creases in the same way.

This picture is taken after making creases in each yellow square.

Please make sure whether there are the creases, which are the green lines and the blue lines in the 4 pictures ago or the 5 pictures ago, in each yellow square.

Cut the paper

Cut your paper after making creases!

If you cut a paper on the dotted lines too, it will get easier to fold big cranes.
However, if you make this model without cutting a paper on the dotted lines, this model will be more beautiful.
Therefore, make this model while folding a paper along the dotted lines.

Cut the paper while referencing the diagram.

Depending on color of the arrows, a length of a cut is different.


The yellow line is the center line.

I cut the paper so that the part which is shown by the blue arrow is 1mm
and the part which is shown by the yellow arrow is 3mm.
Therefore, a connecting part is 4mm.
(I used a 17.5×17.5cm paper.)

On the opposite side, cut the paper while referencing the arrows in the previous picture.

Make sure the direction of each crane

Make cranes so that the orange lines are changed to wings.


After making sure the direction of each crane, make the model – Mitsugaichi.

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!
