Letter With Envelope Included!

So, got bored of the typical letter that has to be folded in four to fit an envelope?!
Let's save trees! 
& be original (: 

* Hands
* Sheet of paper/ Letter
Note: the size of paper used in here is A4 or the usual paper that everyone uses! :D 

So, here it goes guys: 
[Straight up the sheet of paper so it looks as in the image]
First:
Fold in triangles the upper parts of the paper 
Second:
Fold in triangles the lower parts of the paper

It has to look like in the last image, all the 4 cornerns are in triangles (: 

Now, fold eehm.. how to explain it!? 
see the images above (: 

Then, see the triangles that got shaped from the last folding?
Guess what?
Yes, fold it AGAIN to the center (: 

Now, you will have a rectangle as seen above. 
Turn it around & we will KEEP ON FOLDING (: 

Note:
I thought it was going to be a lot easier than it was to explain it with words (:
So I REALLY hope that the images help you understand what I meant! :D
Contact me if there are any doubts

Personally, my favorite part! :D
