Step 1: Lay a
piece of yellow a4-size paper on top of a nice piece of wrapping paper.
Cut the wrapping paper along the a4-paper.
Then tape or glue both papers together.
Step 8: Make
the same kind of folds as in step 6 over these lines, do the same on
the other side of the model.
Step 6: Pull
the part
on the right upwards by making a valley-fold over the short line on the
left and a mountain-fold over the short line on the right.
Make the same folds on the other side, see pink arrow.
Step 11: Pull
both edges outwards, see arrows.
Step 10: Tape
or glue these edges together, do the same on the other side.
Step 9: Tape
or glue these edges together, do the same on the other side of the
model.
Step 5: Fold
these edges straight upwards.

Step 7: Repeat
step 6 on the left.
Step 3: Prefold
in half over this line.
Then turn the model.
Step 2: Valley-fold over
these 4 lines, start with the two outer lines.
Step 4: Prefold
over these lines. All parts have the same width (measured from the
edges or prefolded centerline to the purple lines).
Finally,
press these 4 corners flat between your fingers.
