  • The front right point is triple thickness.
  • The middle right point is double thickness.
  • The rear right point is triple thickness.
  • The free tip of the single-layer triangular flaps is oriented toward 6 o'clock.

Step 27.

Form a valley fold, bringing from bottom to top towards the left, the free tip of the front triangular flap, at the point of intersection with the horizontal lower base of the middle trapezoid.

Clearly mark the fold, from bottom to top, until reaching the inside of the open pocket that has formed, oriented towards the ceiling.

additional information

  • We are forming what will be the right ear of the fox.
  • You can feel a change in thickness along the fold that has just been made.

Step 28.

Slide a finger inside the right middle tip with double thickness.

Fold to the left against the model, along the change in thickness, the part that is on the left of your finger.

Clearly mark the fold and let it stay folded.

additional information

  • For the back flap, a valley fold must be made.

Step 38.

Place the model back on the table in a horizontal position so that the head is on your left and the ears point toward 12 o'clock.

additional information

  • By sliding your finger from left to right on the ceiling-side surface of the fold, you can feel two thickness changes.

Step 39.

Sharply crease the fold, unfold, turn this valley fold into a mountain fold, then unfold.

Step 40.

Remove the model from the table and hold it horizontally between the thumb and forefinger of the left hand.

additional information

  • The fox's head is to the left, the ears toward the ceiling.
  • The thumb and forefinger of the left hand are to the left of the valley/mountain fold created previously.

Step 43.

If the model cannot stand up, a zig-zag fold can be made.

For this, at the point where the back becomes the tail, make a vertical valley fold by bringing the tail from right to left against the body.

Then a few millimeters to the left of this valley fold, make a second valley fold to bring the fox's tail back toward the right of the model.
