Only the front of the square piece of paper is coloured.
Step 1:This is the front of the paper.
Turn the paper.
Step 2:
Make mountain- and valley-folds over the 4 lines.
Unfold each fold after you made one.
Step 3:
First, make a valley-fold over the 2 lines below, on the right.
Then make a mountain-fold over the 2 lines in the middle.
And make a valley-fold over the 2 lines on top, on the left.
Now you get a basic-shape.
Step 4:
Make these 2 folds over the upper 2 layers of the model.
Step 5:
Unfold the folds you made in step 4.
Step 6:
Pull the end at the bottom of the arrow up by making
a valley-fold over the green line.
Step 7:
Press the edges that stand upwards (see arrows) down.
Use the folds you made in step 4 as help-lines when you
do this.
Step 8:
Repeat step 4 to 7 on the backside of the model.
Step 9:
Fold the end at the arrow down by making a valley-fold
over the green line.
Step 10:
Fold the model in half over the green line.
Step 11:
Make a mountain-fold over the line on the right and a valley-fold
over the line on the left. Make these folds over the upper half
of all the layers of the model. Make the same folds on the
backside of the model.
You actually push the end at the arrow a bit to the inside of
the model with these folds.
Step 12:
Pull the end indicated with the arrow a bit downwards.
Then, fold this end up by making a valley fold on the place
that is indicated with the short green line (this line is just
a bit on the right of the arrow).
Step 13:
Repeat step 12 on the end that is indicated with this arrow.
Step 14:
Make an inside reverse fold over the very short green line.
This line is a little bit on the right of the arrow.
You actually pull the end at the arrow to the inside of the
model by making these folds.
Step 15:
Open the model on the bottom-side, see the green arrow.
Step 16:
Make a mountain-fold on the corner in the middle.
Step 17:
Make a mountain-fold on the 2 corners of the shell, see the
short green lines.
Step 18:
Twist the ends at the 2 arrows a few times around.
You can also just fold them 2 times in half over the lenght,
if you like.
The origami snail is ready!
