I saw this article occasionally, showing us how to make a pumpkin of paper~

when I was still very young, I was very fond of Paper Origami... do you think it's interesting?

Halloween Pumpkin Origami

With a square orange origami, fold it in half like so:

Then, fold the paper into half again:

Open it up and you should see this:

Then fold the paper diagonally into a triangle like so:

And fold that in half to get a smaller triangle:

Open up the paper and you should see the following:

Now start to collapse the pre-folded piece of paper. 

You will end up with the folded triangle shown below.  This piece occurs so often in origami that it has its own name, the balloon base.  

Now fold each of the four corners upwards as shown in the next three photos:

Now fold the four horizontal corners into the center as shown:

Use your finger to expand the little pocket as shown below.  You are going to tuck the flap into the pocket. 

However, the flap must first be folded in two to make it small enough for the pocket.

This sequence shows the flap folded, then tucked in.

Now fold and tuck in the other three flaps.

Now fold the front facing 2 flaps together so that the plain side is showing like below:

Now draw your pumpkin face on this plain side:

Finally expand the balloon as shown below...

and Voila! a pumpkin!

Add a "stem" to complete your own pumpkin:

Happy Halloween!
