Cutting a sheet to a paper for origami

First making a perfect square

The sheet

Fold like the picture

Cut in the same place that you see in the picture

And so you have a perfect square

Now for the 2:1 paper, first one thing is size and other is proportion, a paper 20 by 10, or 30 by 15, or 40 by 20 are different sizes of paper but they are the same proportion 2:1.

Now fold the paper in the middle you gonna have one size that is the double of the other, if you want 3 times fold in three; if you want 4 times fold in four(in the middle and in the midle again).

Fold again like the picture now to make the perfect square that will be 2 perfect square

Now cut inthe same place that you see in the picture

diced.

Now you have the 2:1 paper.

Now decorate the paper

 invented a fast draw the art is the origami and not the decoration of the paper.

After the finished origami made with the decorated paper.
