Step 1.
Take a square sheet, lay it flat on the table, in a diamond position.
additional information
- The corners of the square are at the top, right, bottom, and left.
- If it is two-colored, place the colored ceiling side.
Step 2.
Form a valley fold by bringing the right corner over to the left corner.
Make a strong crease, then unfold.
Step 3.
Turn the model over from right to left.
additional information
- The sheet is still in a diamond position.
- The vertical diagonal is a mountain fold.
Step 4.
Form a valley fold by bringing the bottom corner up to the top corner.
Make a strong crease, and leave folded.
additional information
- The fold consists of two large triangular flaps connected by a lower horizontal hinge.
Step 5.
Form a rabbit ear fold with the front flap.
Step 6.
Transform the rabbit ear fold into a squash fold.
additional information
- On the front side of the model, we obtain a kite in double layer
- the long point of the kite is oriented at 12 o'clock
- the short point of the kite is oriented at 6 o'clock, it is single-layer and extends beyond the model
Step 7.
Form two valley folds by folding the edges of the long point of the kite along the vertical axis of symmetry.
Firmly crease these folds and leave folded.
additional information
- The surface of the long point of the kite has been reduced
- The short point of the kite has not changed, it is oriented at 6 o'clock, it is single-layer and extends beyond the model
Step 8.
Turn the model over from bottom to top.
additional information
- The front flap is a large smooth triangle, single thickness, with the free tip oriented at 6 o'clock.
- On the table side, a small tip oriented at 12 o'clock sticks out from the model.
Step 9.
Make an oblique valley fold by bringing the right half of the top horizontal edge from right to left downward, along the vertical axis of symmetry.
Crease well, and leave it folded.
additional information
- The right tip is now at the level of the bottom tip.
Step 10.
Make an oblique valley fold by bringing the left half of the top horizontal edge from left to right downward, along the vertical axis of symmetry.
Crease well, and leave it folded.
additional information
- The left tip is now at the level of the bottom tip.
- The model looks like a square in a diamond position, with one point protruding at 12 o'clock.
- There is a right front flap and a left front flap.
- These two front flaps meet along the vertical axis of symmetry, forming a slit.
Step 11.
Make an oblique valley fold by bringing the left vertical edge of the right front flap from left to right upwards along the top right edge of the fold.
Crease well, and leave it folded.
Step 12.
Make an oblique valley fold by bringing the right vertical edge of the left front flap from right to left upwards along the top left edge of the fold.
Crease well, and leave it folded.
Step 13.
Slide a finger under the multi-layered front flaps to unfold them outward.
additional information
- The front side of the fold has three valley folds:
- A left diagonal valley fold,
- A vertical valley fold,
- And a right diagonal valley fold.
- The fold has a lower left tip, a lower central tip, and a lower right tip.
Step 14.
Form a valley fold by bringing the right edge of the lower right tip along the left edge of that same tip.
Crease well, and leave it folded.
additional information
- We have just reduced the surface of the lower right tip by half.
Step 15.
Form a valley fold by bringing the left edge of the lower left tip along the right edge of that same tip.
Crease well, and leave it folded.
additional information
- We have just reduced the surface of the lower left tip by half.
Step 16.
Through all layers, make a valley fold by bringing the right edge of the lower right tip along the left edge of that same tip.
Crease well, then unfold.
Step 17.
Through all layers, make a valley fold by bringing the left edge of the lower left tip along the right edge of that same tip.
Crease well, then unfold.
Step 18.
Fold the upper right and left parts against the model, using the existing diagonal valley folds described in step 13.
additional information
- The lower right and left tips have a mountain fold on the ceiling side.
Step 19.
Turn the model over from right to left.
additional information
- The vertical axis of symmetry is a mountain.
- The upper tip of the fold is covered by the small kite which is raised on the ceiling side.
Step 20.
Lift the left part of the small kite vertically,
Form an oblique valley fold by bringing the upper left edge of the fold from left to right downward, along the vertical axis of symmetry.
Crease well, then return the left part of the small kite to its original position.
Step 21.
Lift the right part of the small kite vertically,
Form an oblique valley fold by bringing the upper right edge of the fold from right to left downward, along the vertical axis of symmetry.
Crease well, then return the right part of the small kite to its original position.
additional information
- The model consists of:
- On the upper part, the small thickened kite, a front left flap and a front right flap, each marked with a mountain fold,
- A rear left flap and a rear right flap.
Step 22.
Close the model by forming a mountain fold along the vertical axis of symmetry.
Step 23.
Rotate the model a quarter turn to the left
additional information
- The tip of the left point is double thickness.
- The top edge is horizontal.
- Around the middle of the top edge, there is a change in thickness.
Step 24.
At the level of the change in thickness, form an oblique valley fold by bringing the left tip of the model from left to right downward to 6 o'clock.
Crease well and then unfold.
Transform this valley fold into a mountain fold, then unfold.
Transform this valley-mountain fold into an inside reverse fold.
additional information
- The beak, head, neck, and body must be stepped. (The beak and head must not wrap around the neck.)
Step 25.
Turn the model over from bottom to top.
additional information
- The beak and the neck are oriented at 12 o'clock.
- The right part of the model consists of:
- At the front, a long thin multi-layered point oriented at 3 o'clock
- In the middle, a double-layered triangular flap,
- At the back, a long thin multi-layered point oriented at 3 o'clock.
Step 26.
At the neck, on the front and back faces, stretch the first layer to the right to widen the animal's neck.
Step 27.
Slide the left index finger inside the top point to open it,
Push to the left with the right index finger to flip the tip and tilt it to the left.
Continue lowering this tip until it points to 7 o'clock.
Step 28.
Slide a finger inside the long thin tips of the front and back faces, currently pointing to 3 o'clock, to open them.
Lower these long thin tips to 6 o'clock, turning their valley fold into a mountain fold.
Open its legs again, and bring the lower half back to 3 o'clock.
Then bring the 3 o'clock tip to 9 o'clock so that the ends of the tips extend to the left, to form the flippers.
Step 29.
Slide a finger between the two layers of the double-layer triangular middle flap, to open the tail and reverse the horizontal valley fold.
additional information
- the back now covers the rear of the animal.
Step 30.
Fold down on each side to form the back and the wings.
Step 31.
Make a crimp fold to mark the tail.
