Origami Square Base

The origami square base is one of the most important starting points in origami.

Made using simple valley and mountain folds, this base serves as the foundation for many traditional models, including birds, flowers, and boxes.

Let's break this basic fold down step by step!

If you've ever folded an origami crane or a simple paper flower, chances are you've already used the square base!

The origami square base is a basic foundational fold that creates a symmetrical square structure used in many origami models. It is commonly used as a starting point for animals, flowers, and decorative designs, and is formed through simple diagonal folding steps.

This essential origami base is formed by making a few easy folds and then collapsing the paper into a square shape.

It's a fundamental building block for many designs, making it a great fold to master early on.

The square base is sometimes called the preliminary base because it serves as a starting point for more complex bases like the bird base and frog base.

It's created using a mix of valley folds and mountain folds, making it a great way to practice transitioning between different fold types.

Many beginner-friendly origami projects, including flowers, animals, and modular designs, use the square base as a foundation.

Now, let's walk through the steps to make a perfect square base.
