1: Start with a square piece of paper. Cut it in half and use one rectangle.
2: With the white-side of the paper facing up, fold the top-left corner of the paper down.
4: Repeat: fold the bottom-left corner of the paper up.
5: Unfold. You should see a X crease marks.
6: Fold the left side of the paper back along the dash-dotted line as shown in step 5.
8: Fold the left side of the paper towards the right side.
It should collapse along the crease lines made in steps 1 to 6.
Fully collapsed. Begin to make the front legs of the frog: fold the flap up as shown in the next photo.
9: Repeat: fold the other flap up to form the other leg.
10: Shorten the tail end of the frog: fold the right edge of the paper to meet the base if the legs.
11: Make the body more narrow: fold the top of the paper down to the mid-point.
12: Repeat: fold the bottom up to the mid-point.
13: Begin to make the back legs. Next photos are enlarged slightly.
14: Fold the right side of the paper to base of the front legs.
15: Fold the top corner of the leg section to the right.
16: Repeat: fold the bottom corner of the leg section to the right. These will become the back legs.
17:Unfold the leg section a little...
18: Pull out the hidden layer that is underneath.
19: Repeat with the other leg.
20: Press down firmly.
21: Fold the hind leg back
22: Repeat: fold the other leg back.
23: Make the frog springy: fold the model in half so hind legs meet front legs.
24: Fold this section back again forming a zig-zag pleat. Note how legs are closer together compared to image 22.
25: Turn model over. Congratulations! You have made an origami jumping frog.
