First, you need a square sheet of paper.
Now, fold it in half diagonally to make a crease.
Then, unfold it.
Fold one top side edge to meet the center line.
Now, fold the other top side edge and make it meet the center.
Take the tip downward to the bottom line of the preveous two folds.
Flip the paper.
Now, make a little fold to the back and then another fold to the front.
Flip the paper, again.
Fold the left part in a oblique way from the center of the top left edge to the center of the bottom.
Now,, take the little corner...
And open it.
Do the same with the other edge.
Also open the other corner.
It should look like this.
Now, take the tip of the paper.
And fold it behind the two corners.
And now it is ready!!
