Below is a nice video that teach you how to make a fortune teller. Check out the link:
But if you can't spare 10 minutes to watch it, follow my detailed explanation below.
Step one: Shape your paper
Fold one corner of your paper over to the other side to make a square piece. Remove the extra strip of paper by cutting it off. Fold the remaining triangular shape in half to get a smaller triangular shape.
Step 2: Fold into a smaller square
Open your paper and form a square. Fold each corner of the paper in the center to form another, much smaller square. (Some people would prefer folding a rectangular shape first before proceeding further).
Step 3: Fold corners to centers
Turn your paper over and get the corners folded in an opposite direction. Fold it into the center of the opposite side.
Step 4: Form a diamond
Fold your paper into half. Make sure the opening of the fold faces up, pinch the bottom corners of your paper and push it inwards, thereby creating a diamond. Pull out the loose flaps.
Step 5: Create Your Fortunes
Lay flat the cutie-catcher. Make sure you label all of the four different outside flaps with a simple theme. Use any number to label each of the eight smaller flaps after turning it over. Flip up these flaps and scribble a fortune or themed message on every one of the eight inside flaps.
Step 6: Play with the cutie-catcher
You can now enjoy your cutie-catcher.
