What can be folded into rectangular colored paper is as follows:

Rectangles can be folded into paper cranes, paper boats, paper boxes, paper flowers, butterflies, bookmarks, paper airplanes and so on.

1. Paper Crane

Fold the diagonal of the rectangle in half, and then fold it again to get a triangle. You can get a small crane head by folding the two corners of the triangle in half to the center. Finally, fold the crane head down in half, and you can get a complete origami crane.

2. Paper boat

Fold the rectangle in half along the middle, and then fold the corners on both sides towards the center to get a small triangle. You can get the bow of a boat by folding the two corners of the triangle in half towards the center. Finally, fold the bow down in half, and you can get a complete origami boat.

3. Paper box

Fold the rectangle in half along the middle, and then fold the corners on both sides towards the center to get a small square. Fold a square in half along one side and you can get a small rectangle. Finally, fold both sides of the rectangle inward, and you can get a complete origami box.

4. Paper flowers

Fold the rectangle in half along the middle, and then fold the corners on both sides to the center point to get a small triangle. You can get a small petal by folding the two corners of the triangle in half to the center. Finally, fold the petals down in half and you can get a complete origami flower. Origami flowers can be used as decorations for festivals, weddings and other occasions.

5. Paper Butterfly

Fold the rectangular paper in half, fold the two corners along the center line, then fold the two sides inward, turn the two corners outward, and finally spread the wings outward.

6. Paper airplane

Fold the rectangular paper in half along the center line, then fold the two sides separately after opening, fold the triangle down and fold it again, fold the extra triangle up, fold it in half along the center line, and then fold the wings. The origami plane is not only a toy for children, but also an important tool in scientific experiments and competitive competitions.
