How to Make a Preliminary Base
Learn how to make a preliminary base in order to fold cranes, fish and other origami figures that begin with this base.
Step 1 Place the paper on a table with the top side (or colored side) facing down. Make a valley fold through the horizontal middle. Crease the paper and unfold.
Make a valley fold through the vertical center of the paper, crease and unfold.
Flip the paper over so the colored side is facing up. Rotate it so the corners are pointed up/down and to the sides.
Make a diagonal fold, pulling the bottom point up to the top point. Crease firmly and unfold.
Make a second diagonal fold, bringing the left point over to the right point. Crease and unfold.
Grab the paper by the top and bottom points, meeting them together below the paper. Your origami paper should look like the slide photograph.
Next, pull the other two sides down at the same time. The creases you made previously will help the sides collapse correctly.
