澤瀉/Omodaka
“澤瀉/Omodaka” 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.

Omodaka is the model that three cranes are connected to each other with wings.
Connecting parts are long and there is not much space for folding cranes.
Therefore, fold this model carefully!

Preparation of an origami paper
【Size】
a 26x26cm paper or it is bigger than 26cm.
【Kinds】
・Basic origami paper
・Double sided origami paper
・Washi paper
I made this model with a 26x26cm basic origami paper.
If you use a big paper, it will get easier to make this model.
In order to draw lines, prepare a pencil and a ruler as well!
Change to a divisible length by seven
If your paper is changed to a divisible length by seven first,
it will get easier to draw lines.
Therefore, change a vertical length to a divisible length by seven.
If you use a 26x26cm paper, there are the two ways to change size.
The first way is to cut a paper at 1.5cm from an edge so that a vertical length is changed to 24.5cm.
If that’s the case, it will get easier to draw a line.
The second way is to cut a paper at 0.1cm from an edge so that a vertical length is changed to 25.9cm.
If that’s the case, it will get easier to fold this model.
If you use a rectangular paper,
change a long side to a divisible length by seven.
(１)
I drew a line at 0.1cm from the top edge so that the vertical length is changed to 25.9cm.
After drawing a line, cut the paper along the line that you have drawn.
(２)
After cutting the paper, draw lines like this picture.
(３)
“a” is two seventh of the length.
“b” is one seventh of the length.
(If you use a rectangular paper, the length is a long side of your paper.)
If the length is 25.9cm,
“a” is 25.9÷7×2＝7.4cm
“b” is 25.9÷7＝3.7cm
If the length is 24.5cm,
“a” is 24.5÷7×2＝7cm
“b” is 24.5÷7＝3.5cm
(４)
After drawing lines, cut the paper on the blue line.
(５)
Cut the paper like this picture.
(６)
Next steps are making creases at the blue lines.
(７)
Fold the bottom to each line that you have drawn.
(８)
Fold the bottom to the third line from the top like this picture.
(９)
Fold the bottom to the second line from the top like this picture.
(１０)
Fold the bottom to the first line from the top like this picture.
(１１)
Then rotate the paper 180 degrees.
(１２)
Fold the bottom to the first crease and third crease from the top.
(１３)
Fold the bottom to the first crease from the top like this picture.
(１４)
Fold the bottom to the third crease from the top like this picture.
(１５)
Then fold the bottom to the crease that you have made in the previous step.
(１６)
Fold the bottom like this picture.
(１７)
After spreading the paper, it looks like this picture.
Preparing an origami paper is completed!
