piece of paper for folding an origami cake

Step 1:
This paper is for one slice of cake. The size is 7,5x7,5 inch
or 19x19 centimeters. The backside is completely white.
Make a mountain-fold over this line. Step 2:
Fold the model in half over this line. Step 3:
Unfold the model. Step 4:
Repeat step 1 to 3, starting with this line. Step 5:
Prefold the model by making a valley-fold over these 2 lines. Step 6:
Make a valley-fold over these 2 lines.
These lines are parallel to the lines you've prefolded
in step 5. Step 7:
Make an inside reverse fold over the 3 purple lines below,
on the right. Do this by making a mountain-fold over the line
in the middle and a valley-fold over the 2 other lines.

You automatically make a valley-fold over the 2 blue lines
while you make this inside reverse fold.

Step 8:
Repeat step 7 over the 3 purple lines on top in this picture.

Now you automatically make a valley-fold over these 2 blue
lines.

Step 9:
Each arrow indicates a loose triangular piece of 2 layers of
paper. Lock the 2 layers of paper together by pressing them
against each other and making a valley-fold over the middle
of these triangular shaped layers.

(The purple lines in step 11 show the place of the folding
lines on these 2 loose pieces)

Step 10:
Make an inside reverse fold over these 3 purple lines.
Now you automatically make a valley-fold over these
2 blue lines.
You actually just pull the edge at the arrow to the right
by making this inside reverse fold. Step 11:
Lock the 2 layers of paper of the loose piece indicated by
the arrow together. Do this by pressing these 2 layers against
each other and then making a valley-fold over the 2 purple
lines.
(These 2 valley-folds are made in one time, because the layers
are pressed against each other first). Step 12:
Turn the model. Step 13:
One slice of origami cake is ready...
You need 6 of these slices for one completed cake. Step 14:
This paper is for one piece of whipped cream.
The size is about 1,5x1,5 inch or 4x4 centimeters.
If you like large pieces of whipped cream, it's no problemm
to use a larger paper.
The paper is completely white.
Make a valley-fold over this line. Step 15:
Lay the corner at the dot on the left over the backside of the
corner at the dot on the right.
Do this by pulling the 2 corners towards each other, in the
direction of the 2 arrows. Step 16:
Hold the 2 corners of step 15 against each other with
2 fingers, see picture.
First, press the model a little bit inwards at the arrow
on the left. Then, press the model inwards on the places
indicated by the 2 arrows on the right. Step 17:
Push the top of the model downwards from behind, see arrow. Step 18:
Push or pull the 2 ends indicated by the arrows upwards a bit,
so the model gets a flat bottom.
