This instructable will teach you how to make an origami butterfly using a dollar bill.
Step 1: Materials
All you need is a dollar bill, preferably unwrinkled, and your hands.
Step 2: Fold in Half
fold the bill in half lengthwise, short edge to short edge.
Step 3: Fold Corner
Fold the short edge of the top layer to the right edge of the bill. Then unfold.
Step 4: Fold Bottom
Fold the bottom edge so the new crease is at the level of the bottom
end of the crease formed in the last step. Then unfold and open the bill.
Step 5: Mountain Fold the Center
Look carefully at the creases in the middle of the bill. Mountain-fold the outermost creases and move them to meet at the center crease as shown. Then fold the bill in half.
Step 6: Squash Fold
lift the right corner and squash fold the right half as shown.
Step 7: Now the Other Side
Flip the bill over. Now squash-fold the same as the previous side.
Step 8: Fold the Corner Up
Fold the bottom corner up along the white border and the printed edge. Then unfold the bill.
Step 9: Squash the Wings
One side at a time, squash fold the upper left and right halves of the model. Be sure to squash firmly down to the crease line formed in the previous step.
Step 10: Wing Folds
Fold the wings slightly over each other in a z-pattern. The area of the bottom wings will roll over and upwards as you do this.
optional detail: inside reverse fold the corner in the second picture to make the wing appear more rounded.
Step 11: Swivel
Swivel the middle corner over to the crease line on the lower right wing.
Step 12: Now the Left
Fold the left wind over to match the right wing.
Step 13: Fold the Corners
Fold the shown corners to make the wings look more rounded.
Step 14: Fin
open the wings and enjoy your new butterfly.
