1. 

   Step 01

   Fold in half

   Start with the white side facing up. Fold the paper in half horizontally, then unfold.

   You should seeA square with one horizontal centre crease.

2. 

   Step 02

   Fold vertically

   Fold the paper in half vertically from left to right, then unfold.

   You should seeA square with horizontal and vertical centre creases.

3. 

   Step 03

   Fold in half again

   Fold the paper in half horizontally again, then unfold.

   You should seeThe centre creases reinforced and clearly visible.

4. 

   Step 04

   Crease the right corner

   Fold the bottom-right edge to the horizontal centreline. Crease well, then unfold.

   You should seeA diagonal guide crease running from the lower-right area.

5. 

   Step 05

   Crease the left corner

   Fold the bottom-left edge to the horizontal centreline. Crease well, then unfold.

   You should seeMatching diagonal guide creases on both lower sides.

6. 

   Step 06

   Turn the paper over

   Turn the paper over so the other side faces you.

   You should seeThe same rectangle with the lower guide creases showing through.

7. 

   Step 07

   Crease the lower edge

   Fold the bottom edge to the horizontal centreline. Crease well, then unfold.

   You should seeA new horizontal guide crease across the lower half.

8. 

   Step 08

   Turn the paper over

   Turn the paper over again.

   You should seeThe coloured side facing you, ready to collapse the lower section.

9. 

   Step 09

   Collapse the lower section

   Push the bottom left and right sides inward while folding the bottom edge up to meet the horizontal centreline.

   You should seeA layered lower section with two triangular flaps.

10. 

    Step 10

    Fold the top flaps down

    Fold the top flaps downward. There are no exact reference points, so make the frog's front legs symmetrical.

    You should seeTwo matching front legs below the top section.

11. 

    Step 11

    Rotate the model

    Rotate the model 180 degrees.

    You should seeThe front legs at the top and the broad body below.

12. 

    Step 12

    Fold the bottom edge up

    Fold the bottom edge up to the nearest horizontal line.

    You should seeThe lower rectangle shortened by a horizontal fold.

13. 

    Step 13

    Fold the sides inward

    Fold the left and right edges to the vertical centreline.

    You should seeA narrow centre section beneath the front legs.

14. 

    Step 14

    Bring the bottom edge up

    Fold the bottom edge up to meet the point where the front legs connect.

    You should seeA compact body with the front legs meeting at its top.

15. 

    Step 15

    Make guide creases

    Fold the left and right edges of the top flap down to the bottom edge, then unfold them.

    You should seeTwo diagonal guide creases on the top flap.

16. 

    Step 16

    Unfold the top flap

    Unfold the top flap from step 14.

    You should seeThe top flap open, with its new guide creases visible.

17. 

    Step 17

    Open the back legs

    Lift the bottom flaps and push the bottom edge up to meet the point where the front legs connect. The bottom flaps move outward on each side.

    You should seeTwo broad flaps extending outward to become the back legs.

18. 

    Step 18

    Fold the side flaps down

    Fold the left and right flaps down along the existing creases.

    You should seeThe wide back-leg flaps angled down on both sides.

19. 

    Step 19

    Shape the back legs

    Fold the inner edges of the bottom flaps to the nearest crease lines to form the frog's back legs.

    You should seeTwo pointed back legs, aligned symmetrically.

20. 

    Step 20

    Fold up the bottom section

    Fold the bottom section up along the line where the front and back legs meet.

    You should seeA frog shape with four legs gathered around the body.

21. 

    Step 21

    Crease the spring

    Fold the top flap in half from top to bottom. Crease well.

    You should seeA horizontal crease that gives the frog its spring.

22. 

    Step 22

    Turn over and stretch the legs
