Most Origami is made from a square sheet of
paper. In this clip I will show you how to get a perfect square out of any sheet of paper.
Most paper come with straight edges, and perfect ninety-degree angles. So for a paper like
this, we will just simply divide the ninety-degree angle into a forty-five degree angle by folding
this edge to align with this edge, like so. Now we have an excess flap here, and what
we will do is fold it to align with this edge. And at this point, we can either cut off this
excess flap with a right knife, or simply tear it off like this. And open it up and
you have a perfect square. Now you if you have a sheet that’s irregularly shaped, to
get a perfect square, fold it in half as equally as you can. You have a one eighty line. Fold
the one eighty into a ninety degree, and fold the ninety degree into a forty-five degree.
Now note the edge where all the flaps are; make a little notch; a reference mark at the
end of this edge. Open it back up to the ninety-degree angle, and here I will just mark it so you
can see the notches that we made. And at this point, take your ruler, and you can either
cut it between these two points, or fold it between these two points. And get a straight
edge, and here, I am going to cut it. Cut it, and if you open it you have your perfect
