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.
A length of a small square will be three sixteenth of a length of your paper.
If you use a 26x26cm paper,
a length of a small square will be 26×3/16≒4.88cm.
If you use a 17.5×17.5cm paper,
a length of a small square will be 17.5×3/16≒3.28cm.
If you choose a paper so that a length of a small square is 4cm or more,
it will get easier to make this model.
