The basic origami shapes from which various objects, animals, birds, plants are subsequently added. This is the basis of the basics, the first steps in the knowledge of origami.

Many origami start with these shapes, often the first steps are skipped in the descriptions, it is enough to indicate the basic shape. For example, a triangle, and then it is already clear what will be the beginning of the folding of a certain subject.

## Basic Origami Shapes: Square

This is a regular sheet of square paper, of any size.

### Basic Origami Forms: Book

We fold an ordinary square sheet of paper in half, we get a book.

### Basic Origami Shapes: Door

We fold a sheet of square-shaped paper into a book to indicate a fold in the center. And then open and fold the right and left sides inward, aligning them with the fold in the center.

### Basic Origami Shapes: Catamaran

A catamaran can be made in two ways.

**The first way to fold the catamaran**

We start with a square piece of paper, we reach the shape of the previous one, that is, “Door”. Flip over to the other side.

Fold in half.

Fold up the bottom edge of the paper, front and back, to make the fold we need in the middle.

Open the paper.

Open up the corners.

Bend the straight bottom side up, simultaneously directing the corners to the sides.

One part of the catamaran is ready.

Flip over to the other side and follow the same steps.

Open the corners and guide them to the sides, lifting the paper up.

The origami catamaran shape is ready.

**2 way to fold the catamaran**

Prepare a square piece of paper.

Fold the sheet in half, connecting the two opposite corners, straighten it, and then fold it in half again, this time connecting the other two corners.

This will outline two intersecting folds needed for further work.

But we need two more folds. Fold the paper in half, side to side. Straighten with connect the other two sides.

On the paper area, 4 folds-folds intersecting in the center will remain.

Bend all corners in the center.

Open the paper and make an origami “door” shape. That is, bend the sides inward towards the center.

Now fold the top and bottom sides inward.

In the upper part, straighten the corners closed in the middle to the sides, simultaneously directing the top edge of the paper down.

Now do the same for the bottom of the paper.

Fold it into a triangle. And then we connect the other two corners again.

There are intersecting folds.

Flip over to the other side.

Fold in half horizontally.

We open the paper. As you can see, 3 folds have formed on its area, thanks to them it will be easy for us to make the next figure. Direct the sides with a fold to the middle, connecting the two upper and two lower corners along the way.

The result is an origami “double triangle” shape. It is the basis of so many origami. This is the beginning of folding a tulip, a frog, a Christmas tree, an origami crab.
