Origami, the ancient art of paper folding, has long captivated both children and adults alike with its ability to transform simple sheets into intricate, three-dimensional objects. While many associate origami with easy, quick projects like cranes and boats, there's a whole world of "not quite so easy" origami that offers a challenge and a sense of accomplishment.

These intermediate to advanced origami models require patience, precision, and often involve complex base folds and multiple steps. They're perfect for those looking to improve their skills and create more complex origami art. Let's dive into some of these fascinating, yet not-so-easy origami projects.

Understanding Origami Bases
Before tackling more complex origami models, it's crucial to understand and master various origami bases. These are fundamental folds that form the structure of many origami models.

Two essential bases to start with are the square base and the bird base. The square base is the foundation for many origami models, while the bird base is used in more complex designs. Practice these bases until you can fold them effortlessly to build a strong foundation for your origami journey.
Square Base

The square base, also known as the preliminary base, is the most basic and widely used origami base. It's formed by folding a square piece of paper in half diagonally, then unfolding it and folding the four corners to the center.
To create a square base, start with a square piece of paper, typically colored side facing down. Fold it in half diagonally to form a triangle, then unfold it. Next, fold the four corners to the center, creating a smaller square shape. This is the square base, which can be used to create a variety of origami models.
Bird Base

The bird base is a more complex fold, but it's essential for many intermediate and advanced origami models. It's formed by folding a square base into a bird-like shape, with a 'beak' and 'tail' at either end.
To create a bird base, start with a square base. Fold the top layer of the square base down to the bottom, creasing well. Unfold this fold, then fold the top two corners down to the center crease. Next, fold the top layer of the new square base down to the bottom, creasing well. This should result in a bird-like shape with a 'beak' and 'tail'.
Intermediate Origami Models

Once you've mastered the basic origami bases, you're ready to tackle some intermediate models. These models require more steps and may involve new techniques, but they're still accessible with patience and practice.
One popular intermediate origami model is the Modular Dragon. This model involves creating multiple origami scales, which are then assembled to form a dragon. It's a great project for learning how to create modular origami, where multiple pieces are assembled to create a larger structure.




















Modular Dragon
The Modular Dragon is a classic intermediate origami model that's well worth the effort. It involves creating origami scales, which are then assembled to form the dragon's body. The head and tail are separate pieces that are added on.
To create the scales, start with a square piece of paper. Fold it in half diagonally to form a triangle, then unfold it. Next, fold the four corners to the center, creating a smaller square shape. Fold the top and bottom edges to the center, then unfold these folds. Fold the four corners to the center again, creating a smaller kite shape. Finally, fold the top and bottom edges to the center, creasing well. This is the basic scale unit.
Lily
Another intermediate origami model is the Lily. This model involves creating a series of petals that are then assembled to form a lily flower. It's a great project for learning how to create curved shapes in origami.
To create the lily petals, start with a square piece of paper. Fold it in half diagonally to form a triangle, then unfold it. Next, fold the four corners to the center, creating a smaller square shape. Fold the top and bottom edges to the center, then unfold these folds. Fold the four corners to the center again, creating a smaller kite shape. Finally, fold the top and bottom edges to the center, then unfold these folds. Fold the four corners to the center one more time, creating a smaller square shape. This is the basic petal unit.
Advanced Origami Models
Once you've mastered intermediate origami models, you might be ready to tackle some advanced projects. These models require a high level of skill and patience, but they're incredibly rewarding to create.
One of the most challenging and rewarding advanced origami models is the Modular Supernova. This model involves creating hundreds of origami units, which are then assembled to form a stunning, intricate supernova.
Modular Supernova
The Modular Supernova is a complex origami model that's well beyond the scope of this article. However, it's a great goal to work towards as you improve your origami skills. The model involves creating a variety of origami units, including petals, leaves, and spirals, which are then assembled to form the supernova.
To start learning the Modular Supernova, it's recommended to begin with the simpler Modular Flower model. This model uses many of the same techniques as the supernova, but it's much simpler and therefore a good starting point.
Tessellations
Tessellations are another advanced origami technique that involves creating intricate patterns by folding multiple origami units together. These models can be incredibly complex and time-consuming, but they result in stunning, geometric patterns.
To create a tessellation, you'll typically start by creating a series of origami units, such as squares or triangles. These units are then folded and assembled in a specific pattern to create the tessellation. Some tessellations can be quite complex, involving hundreds of individual units.
Origami is a journey of continuous learning and improvement. Whether you're a beginner just starting with the square base or an experienced folder tackling advanced tessellations, there's always more to explore in the world of origami. So keep practicing, keep learning, and most importantly, keep having fun with your folding!
