First you need to get a square sheet of paper (Must be right angles)... You fold the paper in to four boxes. Then you get a corner at the top of the paper and bring the corner to the center of the paper. Do that with al of the sides. Once you have finished that, flip the paper over, you will see four boxes just like how you folded it. Fold the corners back just like the begining. Then you flip it over and you will see another for squares with flaps. Fold the paper in half and unfold it. Then you put your fingers in the flaps and open them. The your fortune teller is created! Thank you for reading!! :DD
