The Japanese art of folding paper is called "origami" and paper money can be used as well. There are many different shapes and ways to fold paper money into interesting and entertaining shapes for gift-giving or just for fun. Start learning how to fold paper money by choosing a basic heart shape. You can practice with a piece of paper cut in the shape of a dollar bill until you perfect your technique.
Fold the bill in half lengthwise, crease the fold and unfold. Fold the bill in half width-wise, crease the fold and unfold.
Place the bill on a flat surface, with the back of the bill facing up. Fold the bottom of the bill up so the bottom edge aligns with the lengthwise centre crease. Crease this fold well and leave it folded.
Bring the right bottom corner of the bill up toward the centre of the bill and align the bottom edge of the bill with the width-wise centre crease. Crease this fold well. Repeat the same fold with the left bottom corner of the bill.
Turn the bill over and fold in the right edge of the bill so the right side edge of the bill is even with the width-wise centre crease of the bill. Repeat with the left side edge of the bill and crease these folds well.
Notice the top left and right flaps. Fold both flaps down halfway to leave the top flaps half the original size.
Fold both outer and inner corners of the two top flaps in at a diagonal to create two pointed tops of the heart.
Turn the bill over to show a simple heart shape.
