How to make: An Origami Ball (inflatable)

 This one is a lot like the Inflatable Rabbit (just a little simpler). Start with your paper in front of you, color side down.

 Then fold in half, and crease well.

 Then unfold your paper.

 Rotate.

 And fold again.

 It should look like this when you open it.

 Then fold it diagonally.

 Open.

 And fold the other way.

 It should look like this.

 Then fold your paper into a triangle (also known as a squash fold).

Then fold the corner up to the top of your triangle.

 Repeat with other corner, it should look like a diamond in the center.

 Then fold the outer tip of the diamond into the center.

 Repeat with other tip.

Flip over.

 And repeat the earlier steps (fold into diamond).

 (fold tips to the center).

 Then you blow into the tiny hole at the top.

Now you have your ball (remember to crease well, or it will not turn out).
