Another of my personal origami dollar creations is the seahorse. This is a bit trickier than the dollar bill penguin. I created this from my memory of what a seahorse looks like, and as a result not all the details are correct. For instance, the tail I made curl backwards and they actually curl forward. So the pictures I've taken are of the reverse tail configuration, but the directions I put down show the more correct forward curl.
Anyway, all that being said, I'm posting directions on how to make the seahorse. Let me know how it goes!
Step 1: Fold the dollar bill in half lengthways, and unfold.
Step 2: Fold the corners to the center-line, similar to how you would start folding an airplane.
Step 3: Fold the corners again towards the center-line, again like in an airplane.
Step 4: Fold the oppose corners to the center-line.
The next few steps are preparation for a rabbit fold. Both of the triangular flaps will get a rabbit ear fold.
Step 5: Fold the edge of the triangular flap that lies on the center line to the hypotenuse of the triangle. The unfold.
Step 6: The the edge perpendicular to the center-line to the hypotenuse and then unfold.
Step 7: Create the rabbit ear by folding along the creases created in the last two steps. The right angle portion of the flap gets folded in half and pulled so that it points away from the end of the bill.
Step 8: Repeat the rabbit fold on the opposite flap.
Step 9: Fold the bill in half lengthwise, so that the folds just created lay inside the model.
Step 10: Fold the edge with the rabbit ear folds to the centerline of the model. This will expose the rabbit ears. Repeat behind.
Step 11: Rotate the model so that the rabbit ears are towards the top.
Step 12: The next step is to crimp fold the top of the model. This will form the head. The crimp fold can be created by grabbing the tip of the model and rotating it forward while holding the body with the other hand. It's really just a couple of reverse folds.
Step 13: Fold the ears forward. The ears were created by the rabbit ear fold earlier. Fold them so that they stick straight upwards. They can be curled slightly for appearance.
Step 14: Inside reverse fold the tip of the nose downward.
Step 15: Inside reverse fold the tip back upwards. Make the fold so that it lies just below the line of the jaw. This will create a flared appearance at the nose. You can just the tip a bit to make it stick out less.
Step 16: Crimp fold the body. This can be done with an inside reverse fold to bring the tail upwards and then a second reverse fold to move the tail back downward.
Step 17: This step will form the fins and thin the tail. Start by thinning the tail. The fin gets formed with a rabbit ear fold. As you thin the tail, pinch the corner that will form the fin. After this step the model will not lie flat.
The next few steps form the tail curl. Diagrammed below are the steps to form the tail the "correct" direction.
Step 18: Inside reverse fold the tail forward.
Step 19: Outside reverse fold the end of the tail upward.
Step 20: Fold the tip of the tail inward to complete the model.
