Hello and Welcome to our Origami Ninja Star video.
This is a modular piece of origami, so we're going to start with two (2) pieces of origami
paper, color side down.
First on one piece make a valley fold
just like this; otherwise known as a book fold.
And you want to crease the paper pretty well.
Then unfold.
Now repeat the same
book fold and unfold
on the second color.
Crease that well.
And unfold it.
Now you're going to do a cupboard fold.
Fold the left and right edges of the piece
to that crease you just made.
So when you're done, it'll kinda look like the
doors of a cupboard
that's why it's called a cupboard fold.
Now repeat that on the other
piece of paper.
Now we're going to fold each of these
pieces in half lengthwise.
Now we're going to flip the left paper over so that both
of the openings are facing towards
the left.
Now we're going to do a simple valley fold
across the middle
of each piece.
Make a nice crease line
then unfold.
Do that on the other paper.
Now at this point things will get more interesting....
So we're going to do a  valley fold
on the top of the left piece
from right to left as we're showing
here
at a forty five degree angle.
Now repeat that on the bottom side of the paper
 
but going the opposite direction,
so this time from left to
right
and again at 45 degrees.
Now on the other piece of paper you want
to do the exact opposite, and the goal here is
to
create a mirror image of the first piece, so
we're going from left to right on
the top fold
but on the bottom we're going to go from right to left.
When you're done, the two (2) pieces should look like this.
Now we're gonna make another by valley fold.
Bring the top corner
across to the right, as we're showing here.
Crease that as sharply as you can.
Now the bottom of the paper is going to
be opposite so
go from
bottom across the left.
So that's the left piece
and you probably guessed we're going to do the opposite
on the other piece.
The top
comes across to the left
and the bottom goes across to the right.
So again, two (2) mirror images of each other
The piece on the left, you want to flip over
just like this
so that the rectangular center
is pointing straight up and down
so that piece right there.
Now the piece on the right
we'll rotate so that the
rectangular center is
left to right
and we'll overlap the two like this.
So now we're going to start tucking the
pieces together.  First we
valley fold
the first piece
over from the left.
Fold this downwards and
tuck it into the second piece
just like that.
Then with the other corner
on the right there, fold up
and tuck it under.
That corner goes into that slot right there.
 
Bend it a little bit
and tuck it under
and flatten out.
 
Now we're going to need to
flip the piece over
and we're going to be tucking in
the
second color, yellow in this case
on the back side.
Start with the first corner
valley fold.
The other corner will be folded
on the opposite side.
Here is where it gets tricky. You need to tuck this
corner right under
the flap there
then the same on the other side.
And get them both in a little bit,
and then
start working the paper in.
Push it in, don't
force it, just gently
slide it in, till it's in all the way.
And then you want to go around the piece
and make sure all the joints are tight and tucked in.
 
And there you have it!
Your completed Origami Ninja Star.  Have Fun!
