Only the front of the square piece of paper is coloured.
Step 1:This is the front of the paper.
Make mountain- and valley-folds over the 4 lines.
Unfold each fold after you made one.
Then, turn the paper.
Step 2:
Make a valley-fold over the line on the left and
a mountain-fold over the line on the right.
The piece between the 2 lines will go a bit to the left
after you made these folds.
Step 3:
Repeat step 2 on the same other 3 pieces of the model.
In the picture on the left are the folds you have to make.
Step 4:
Press the 2 pieces indicated with the dots against each
other and lock them together by making a fold on the
corner.
Step 5:
The big arrow indicates the result of the folds in step 4.
Repeat step 4 on the same other 3 places of the model
(see the small arrows).
Step 6:
Fold the 4 triangular ends to the inside of the model
by making a valley-fold over the 4 lines.
Step 7:
Place the model upright.
Step 8:
Make a mountain-fold on the 4 open corners of the pyramid.
See the 3 purple lines. The 4th purple line is on the
backside of the model.
The pyramid is ready!
