Step 1:
The other side of this paper is completely white. Prefold in half four times.

Step 2:
Fold the corners to the center.

Step 3:
Turn the model.

Step 4:
First, make a valley-fold over the 2 lines at the bottom-right. Then, make a mountain-fold over the 2 lines in the middle. And make a valley-fold over the 2 lines at the top-left.

Step 5:
Pull the piece indicated by the arrow upwards by making a valley-fold over the yellow line.

Step 6:
Hold the piece between two fingers, see large arrows. Then, press this piece flat from above with your other hand, see small arrow.

Step 7:
Make a valley-fold over these 2 lines.

Step 8:
Unfold the folds of step 7.

Step 9:
Pull the edge indicated by the arrow downwards by making a valley-fold over the yellow line.

Step 10:
Press the edges indicated by the arrows flat from above.

Step 11:
Fold the triangular piece below the yellow line upwards by making a valley-fold over this line.

Step 12:
Repeat steps 6 to 11 on the other 3 loose pieces.

Step 13:
Pull the 2 ends at the bottom of the arrows outwards, in the direction of these arrows.

Step 14:
Fold the triangular piece above the yellow line to the inside of the model by making a mountain-fold over this line.

Step 15:
Push the 2 ends towards each other again, see arrows.

Step 16:
Repeat steps 13 to 15 on the other 3 same places of the model.

Step 17:
Push or pull the 2 pieces indicated by the arrows upwards by making a valley-fold over the yellow line.

Step 18:
Pull the upper layer of paper loose from the rest of the model. Start pulling at the bottom of the edges, see arrows.

Step 19:
Make a valley-fold over these (prefolded) lines.

Step 20:
Now you've made an extra end. Fold this end upwards by making a valley-fold over the yellow line.

Step 21:
Repeat steps 17 to 20 on the other 3 same places of the model.

Step 22:
Fold the piece on the right of the yellow line to the left by making a valley-fold over this line.

Step 23:
Make a valley-fold over this line. Fold over all layers of the loose piece.

Step 24:
Repeat step 23 on the same place at the backside of the model.

Step 25:
Make a valley-fold over this line.

Step 26:
Unfold the fold of step 25.
Then open the model by pulling the ends outwards, see arrows.

Step 27:
Fold the center of the model downwards by making mountain-folds over these lines. These lines are prefolded in step 25

Step 28:
Press the model inwards on the places indicated by the arrows. No new folding lines have to be made to do this.

Step 29:
Now the model has the same shape as in step 25 again, but the top is folded downwards.
Fold the piece on the left of the yellow line to the right by making a valley-fold over this line.

Step 30:
Fold the loose piece below the yellow line upwards by making a valley-fold over this line.

Step 31:
Make a valley-fold over this line.

Step 32:
Prefold over this line.

Step 33:
Make a mountain-fold over the yellow line.
Then pull the tip of the white end downwards, see arrows.

Step 34:
Push the place indicated by the arrow flat.
Then, make a valley-fold over the yellow line.

Step 35:
Make a valley-fold over this line.

Step 36:
And make a valley-fold over this short line.

Step 37:
Repeat steps 29 to 36 on the other side of the model.

Step 38:
This is the backside of the elephant.
Make an inside reverse fold over these 3 lines.

Step 39:
Hold the model the same as I do.
Then press the tail flat with your other hand, see arrow.

Step 40:
Make a mountain-fold over this line.

Step 41:
Curl the tip of the tail upwards by just rolling it up.

Step 42:
Press the place indicated by the arrows inwards. Then make a mountain-fold over the short yellow line.

Step 43:
Repeat step 42 on the other leg, see arrow.

Step 44:
Press the place indicated by the arrows down by making a mountain-fold over the 2 yellow lines.

Step 45:
Make a mountain-fold over the short yellow line.

Step 46:
Repeat steps 44 and 45 on the other side of the model, see arrow.

Step 47:
Pull the tip of the trunk to the left by making an inside reverse fold over these lines.
(Make a valley-fold on the same place as the line on the left at the layer below)

Step 48:
Trunk Down......

Step 49:
This is the same picture as in step 47

Pull the trunk upwards by making an inside reverse fold over these lines.
(Make a valley-fold on the same place as the upper-line at the layer below)

Step 50:
And make another inside reverse fold over these lines, by pulling the tip of the trunk downwards.

Trunk up!
