Start with a 7 inch square of origami paper-- smaller becomes more difficult.
Fold in half to make a rectangle with your desired side facing out (for us it's the patterned side as shown). Then pull the corner to the mid crease, bisecting the corner shown in the upper right. Unfold and repeat with the upper left corner, then unfold.

Refold the upper left corner along the crease you just made. Bisect the creased edge by bringing the upper right corner point over to the left edge of the paper, right where the fold is. Crease the new fold created at the right side of the paper.
Completely unfold the paper and repeat the above on the other side, starting with the upper right corner. Unfold and check that your creases match the photo, then spin your paper 180 degrees so the top edge is now at the bottom edge.

Your new creases can help guide you-- let the right and left sides come together while the bottom edge folds up, as shown.
Swing the right "wing" to the left, hinging at the center line. Bring the point of this wing down to meet the bottom center point and crease your fold. Repeat with the other wing.
Then create a valley fold in each of the "inner triangles," bringing the creased edges you just made to the center line and flatten the form as shown.

Open up one of the flaps and fold the flap's bottom edge up to meet the flap's outer edge.
Use this new crease to invert the center bottom corner of the flap and re-flatten, as shown.
Repeat on the other side.

Repeat on the other side.
In this step the frog begins to become 3D. See the remaining back side of the paper showing? Fold this triangle over itself beginning with the point of the front foot and easing into the center of the frog, allowing the top end of the paper to begin to curve.
Fold each front leg in half lengthwise to give them shape.

Turn the frog over and bend 1/4 of the arm forward and invert the "hand" so it is able to stand.
Turn your attention to the broad back end of the frog. See those bits of paper showing out from under the cape? Fold them to the interior of the frog to hide them.

Turn your frog over and fold the body 1/3 of the way up.
Fold each leg over to make the hip. The exact angle isn't important, just keep the legs consistent.
Fold each leg back onto itself and create another crease parallel to the hip.
You can stop here for a perfectly respectable frog! If you want to create extra bounce and a more 3D form, unfold the bottom half of the frog and then fold the whole frog in half at its center back. Bend the "belly" to one side to create an inversion that helps tuck the frog's rear under itself while doming the back.

Return the frog to its unfolded state and invert the creases you just made while helping the back become a dome. Then re-fold the back legs for an extra hippity-hoppity frog.
If you're making a pond scene with ITO as described on the next page, prepare the led by taping it inside the frog with copper tape that extends from each lead to the rear feet.
To carry a battery on board, simply sandwich the LED leads around the battery (flip it around until it lights up) and tape the assembly inside the frog. Adjust the angle of the LED to suit your taste.

Here is the frog photographed from underneath the clear ITO!
