On this page you can learn how to fold the depicted bull head.
Instructions
-
Take a square sheet of paper and fold it along all four symmetry axes. I recommend to fold the diagonals in both directions.
-
Put the edges of the sheet on top of the diagonals (all eight possibilities) and crease the paper from the corner till the middle axis:
-
Use the folds just made to shape the paper as shown:
It is a form with four tips. -
Bend one of the tips backward and then fold it along the lines shown in red so that two isosceles triangles are formed:
-
Fold the tip, as shown, along the red lines so that a flat pentagon is formed:
-
Fold the pentagon in along its middle axis:
-
Along the marked line, fold two small triangles outward:
That will be the chin. -
Use a reverse fold
to fold the two opposed remaining tips to the back:
Because such a reverse fold changes the direction of the diagonal fold, it made sense to crease the diagonals in both directions. -
Fold both tips to the front using inside reverse folds:
These will be the horns. -
Fold the horns upward at a right angle, as close to their base as there is space:
-
Where the horns come out, fold the last tip to the front. Only the upper layer of the paper should be creased;
the layer on the other side remains uncreased, so that it bulges:
-
Make another crease parallel to the first one:
-
You can pinch the lower parts of the sides of the face to make creases that define the zygomatic bones:
-
Fold the tip of the face to the front, as shown:
If you pinch it from the sides, the edge of the paper should fold back on itself:
-
Parallel to the creases just made (green), make a reverse fold (red):
Now the face is done. -
On the backside there is a corner (the midpoint of the paper). Pinch it from above and below and fold it over downward:
-
The two corners on the rear top of the head are folded upward:
-
Now we are basically done, but the horns possibly do not want to stay in shape:
In that case, the corners at the front of the base of the horns should be folded over:
-
Done:
If you did everything right, the tip of the process originating from the chin should come to lie in the crease of the face:
