I used a 7x15cm piece of recycled paper.

Follow the creases on the picture...

... folding like this

Fold down one of the sides till de central (vertical) line

Now flatten this last fold. (See that the creases stay aligned)
Turn it (as a book page) and repeat the step with the other side.

That's the appearence after both sides have been folded

Turn all these "pages" to one side, and fold up to the central line the lower edge of both sides (see the picture) just to crease

Unfold step "7" and now make the lower vertex together with the upper one. This is a little critical, but the creases will help you to fold in the right place

That's the appearence after step "8".
Remember you'll have to turn these folds aside (as a book) and repeat the same with the other side

You'll obtain something like this

Another difficult step. The little triangle that appeared on last step will be refolded inwards

Take a breath... It's easier from now on.
Make a "z" fold, respecting the proportion |_2/3_|1/3|

Fold down to the central line both sides. (that's the same fold we had on the first project "Rochen/Stingray")

You'll have to adjust the paper (see the picture)

We have now armadillo's head and long ears

Now, the tail...

As you can see, it's the same fold of step "12" applied to the lower part of the paper

Now it'a a piece of cake.

Make parallel superimposed folds, like a concertina... See the picture

Bend down the edge of both sides. (The better way to do this is using a ruller) This will help to mantain the folds done on step "15"

(*Note that I turned it upside down for you to see what I describe on this step)

Fold the whole piece down on the central axis.
Hold the snout and open its ears (pressing)
Hold the lower part and stretch carefully the upper part, bending the body (carapace) of the armadillo.
Ins't it cute??
