Origami Ball

This going to teach you how to make one of those cool origami balls.
Let's get started.

Place a square piece of origami paper on a hard surface, color side down. Fold paper in half, corner to corner, like a taco. Crease and unfold.

Repeat the fold in Step 1 using the opposite corners. Crease and unfold. Your creases should make an "X" on your paper.

Fold paper in half like a hot dog bun by taking the top edge to the bottom edge. Crease well.

Holding the left side of the paper down, push the right folded edge down and in so that it tucks into the center. Flatten. Repeat with the left folded edge.

Take the bottom right point of the top layer triangle only and take it up to the top of the triangle. Crease. Repeat with the left side. You should have a diamond shape on top now.

Take the right point of the diamond and fold it in to the center line. Crease. Repeat with the left point of the diamond.

Notice that the folds you made in Step 6 created two pockets. Just behind the pocket is a triangular flap of paper. Tuck that flap into the pocket as far as you can. Do this for both sides.

Turn origami over. Repeat Steps 5, 6 and 7 on the other side.

There is a small opening or hole in one end of the origami. Rotate the paper so that the origami is at the top.

Place your index fingers between the flaps on either side. Blow into the hole...

...The origami expands and you have made a paper ball!
