Turn the paper diagonally and fold down into a triangle

Fold in half again, left to right

Spread the inside out (like in the picture)

And flatten, it should look like this. Now turn it over

This is the back. Flip the triangle part to the other side

So now it looks like this

Flip it over, and do the same steps shown in the video to that side

Now flip over and do the same thing shown in the video to that side (fold top layer to the center line.)

Have fun! Tell me how yours works out, or ask any questions in the comments. If you need a video of a step, post a comment and I'll put up a video of it :)
