Origami, the ancient Japanese art of paper folding, offers a myriad of creative and functional projects. One such practical and aesthetically pleasing creation is the origami envelope. This guide will walk you through the steps to make an origami envelope using a simple rectangle paper, perfect for storing small notes or precious mementos.

Before we dive into the steps, ensure you have a square of paper. If you don't, you can easily create one by folding a rectangle in half diagonally, then unfolding it to create a square. Now, let's begin our origami journey.

Preparing Your Paper
Start with a square piece of paper. For this tutorial, we'll use a 6x6 inch (15x15 cm) paper. The larger the paper, the larger your envelope will be.

If your paper isn't already square, follow these steps to create one:
- Fold the paper in half diagonally to form a triangle.
- Unfold the paper, then fold it in half along the other diagonal to create an 'X' crease.
- Fold the paper in half horizontally, then unfold it.
- Fold the paper in half vertically, then unfold it. You should now have a square.

Creating the Envelope Base
Now that you have a square, let's begin folding the envelope base.
1. Fold the paper in half diagonally to form a triangle. Crease well, then unfold it.

2. Fold the paper in half horizontally, then unfold it.
3. Fold the paper in half vertically, then unfold it. You should now have an 'X' crease on your paper.
Forming the Envelope Sides

Next, we'll create the sides of the envelope.
1. Fold the top left corner to meet the center vertical line. Repeat this on the top right corner.




















2. Fold the bottom left corner to meet the center vertical line. Repeat this on the bottom right corner.
3. You should now have a smaller square with four flaps. Fold each flap in half towards the center.
Assembling the Envelope
We're almost done! Now, let's assemble the envelope.
1. Fold the top left corner to meet the center horizontal line. Repeat this on the top right corner.
2. Fold the bottom left corner to meet the center horizontal line. Repeat this on the bottom right corner.
3. Fold the top of the envelope down to create a flap. You can make it as large or small as you like.
4. Fold the sides of the envelope inwards to create the final shape. Your origami envelope is now complete!
Decorating Your Envelope
To make your envelope even more special, consider decorating it. You could draw on it, add stickers, or even use colored paper for a vibrant look.
1. Before you start decorating, consider the design you want. It could be a simple pattern, a drawing, or even a quote.
2. Use markers, colored pencils, or paint to decorate your envelope. If you're using stickers, apply them now.
3. Once you're done, your origami envelope is ready to use or gift!
Origami is a rewarding hobby that allows you to create beautiful, functional items like this envelope. Practice makes perfect, so don't hesitate to try again if your first few attempts aren't perfect. Happy folding!
