Origami bases aren't as much fun to make as folding a cute paper crane or a pretty origami butterfly, but bases are the "building blocks" upon which the study of paper folding is built.
Not all origami models will begin by creating a well-recognized base, but many do. In fact, some resources for more advanced origami enthusiasts will simply say, "Create a bird base" instead of explaining all of the steps that are involved in making this form. Therefore, it is helpful to have a rudimentary understanding of the most popular origami base forms before beginning any serious origami study.

Origami Blintz Base
A blintz base is made by folding each corner of a square sheet of paper to the center. Folding and unfolding the reference creases is sometimes recommended to increase the accuracy of the base form. The name for a blintz base comes from the fact that it resembles a pancake-like dish called a blintz that is popular in parts of Eastern Europe.

Origami Balloon Base
To fold a balloon base, begin with the colored side of your origami paper face up. Fold in half horizontally. Crease firmly, then unfold. Fold in half vertically. Crease firmly, then unfold. Flip the paper over so the patterned or colored side is facing down. Fold the paper in half diagonally. Crease firmly, then unfold. Fold the paper in half diagonally from the other direction. Crease firmly, then unfold. Using the middle vertical folds, collapse the paper into a triangle shape.
It is interesting to note that the crease pattern for making a balloon base is the exact opposite of the one for folding a square base. Sometimes, a balloon base is called a waterbomb base.

Origami Square Base
A square base is also known as a basic flower form because it is used to make many different types of origami flowers. Another common name for the square base is the preliminary base.
To make a square base, place your paper on the table with the colored or patterned side up. Fold it in half diagonally and open. Then, fold the paper in half along the diagonal the other way. Turn the paper over to the opposite side. Fold the paper in half horizontally, crease well, and open. Then, fold again in the other direction.
Using these creases, bring the top three corners down towards the bottom of the paper. Flatten the paper to complete your square base.

Origami Bird Base
A bird base is a square base plus two petal folds. It is called a bird base because it is the basis of the origami crane, one of the most famous origami models of all times.
To turn a square base into a bird base, fold the top triangular flaps into the center and unfold. Fold the top of the model downwards, crease well, and then unfold. Open the upper flap, pressing the sides of the model inwards at the same time. Flatten down, creasing well. Flip the paper over and repeat the petal folds on the other side.
