In this Arts & Crafts video tutorial, Ana Maria, Origami artist, will show you how to fold an origami paper pyramid. For this you will need a square piece of paper; preferably colored. Fold the paper in half, open it up and fold in half in the other direction. Open up and fold all corners to the center point of the paper. Now fold it in half in both directions. Open up the last fold and fold one of the edges inwards. Open up again, unfold the adjacent flap and lock the flap down as shown in the video and your pyramid is ready.
