I used a small paper for this fan, but you can also take a larger piece of paper.
Only the front of the square piece of paper has to be coloured.
Step
1:Make a mountain-fold over the red line.
Step 2:
Make a valley-fold over this line.
Step 3:
Fold the piece on the right to the back by making
a mountain-fold over the red line.
Step 4:
Repeat steps 2 and 3 until the model looks like
the figure in step 5.
If you use a larger piece of paper, you have to repeat
steps 2 and 3 a little more.
Step 5:
Hold the model with one hand at the 2 small arrows
