Origami Mountain And Valley Folds
Have you ever wondered what a sheet of paper can become? With Origami, a few simple folds unlock a world of creativity. From playful animals to geometric wonders, all it takes is a square and a curious mind.
Mountain Fold
Fold the paper upwards to create a ridge that resembles an upside-down “V.” A dash-dot-dot line indicates where to make a mountain fold. The symbol line of a mountain fold is a dash-dot-dot line.
How to make a mountain fold
Start with a piece of paper. Fold the paper in half, aligning opposite corners. If you make the white side up, you will fold the wrapper backward (along with the direction of the arrow), making the colored side inside and the white side outside.
Unfold the paper to reveal a creased diagonal line and then you will find it looks like a mountain. That’s why it is called mountain fold.
Valley Fold
Fold the paper downwards to create a valley that resembles the letter “V.” A dashed line indicates where to make a valley fold. The symbol line of the valley fold is a dashed line.
How to make a valley fold
Begin with a piece of paper with one side white and one side colored. Place the white side up. Fold the paper in half, aligning opposite corners. If you make the white side up, you will fold the wrapper frontward, making the colored side outside.
Unfold the paper to reveal a creased diagonal line. The paper looks like a valley now, so it is called Valley Fold.
Mountain fold and valley fold are two fundamental fold types that form the foundation of virtually all origami models.
