skip the next 4 pages if you already have square shaped paper

Take an a4 piece of paper and fold a triangle like this

Fold the rectangle shaped piece of paper that's left over

So it should look like this from the back

Fold it back on itself then rip the rectangle off or use scissors

And now we're ready to begin! Take the corners of your paper which have a fold line down the middle of them...

And bring them together then fold

Like so

Open up your sheet of paper and fold all the corners into the center

Like this. Don't worry if their not perfectly in the middle it dosn't matter that much if their a bit off

Flip it over and fold all the corners into the middle again

Like this. Again it dosn't have to be perfect

If you fold it in half like this it will help you open it up better but you don't have to

Now add colours or words or number to the outside and inside

And in each flap add a little corny fortune or yes and no answer. Hope this helped :D
