Hello, and welcome to our Origami Box video.  This is the very basic origami box
or "masu".  You'll start with a square
of origami paper, with the color side down.
First you'll make a Mountain Fold; fold the paper in half as we're showing here.  Crease the edge well.  Then you'll make another mountain fold, similar to the first
at ninety degrees.
Now unfold the paper and we'll use those crease lines that we just made as guides
to fold each of the four corners of the paper towards the center, just like we're showing here.
So start with two of the corners, and fold them in and line them up carefully; hold down the center
with one finger and crease the edges as we're showing here.
Now do this for the other two (2) corners
and also crease those edges well.
Next we'll fold in two (2) of those edges to the center
just like this
Now we're going to fold the paper in half
Now unfold the paper, and fold the two (2) short edges towards that center line crease that you just made.
Now we're going to unfold the last two-and-a-half steps.  So unfold that, then take the sides out, then two (2) of the corners will go out like this.
Now we're going to start folding in the sides out the box.  You'll start with two of
corners as we're showing here
fold in the top corners.  As we do this we'll actually need to reverse
the direction of the fold on the corner of the box
so this piece will go out like.  And here
on the other side as well.
When that's done, fold in the top flap like
this, all the way into the box.
Rotate the piece around, and we'll repeat that step.  And it was kind of tricky so let's zoom in and look
at it closely. So what we're trying to do is
fold in the sides, and as we do this vertical line
here, this fold is going to be
reversed.
So start folding in the corner like this, and push that corner out, and then re-crease it as we're showing here.
Now do that on the other side.  This piece goes in, re-crease this piece.
 
And now fold in the remaining flap into the box.
Crease all the edges.
And there you have it: your Origami Box is complete.  Enjoy!
