Blintz-fold-crane means a crane which is made from a blintz-base. (I named it.)
Blintz-base means the shape which four corners are folded to the center point. The picture is down below.
There are two types of blintz-fold-crane. I named them inside-blintz-crane and outside-blintz-crane.
Inside-blintz-crane looks the same as a basic paper crane. Outside-blintz-crane is a crane that you can see a liner or the back side.
Before folding a basic-crane for connecting-cranes, make basic-creases down below.
Before folding a blintz-fold-crane, make creases down below.
I named the creases “blintz-crane-creases”.
Also, the creases of inside-blintz-crane are “inside-blintz-crane-creases”. the creases of outside-blintz-crane are “outside-blintz-crane-creases”. (Make creases on the same part before folding an inside-blintz-crane or outside-blintz-crane. However, make some creases in the different direction.)
Before folding Renzuru which is included blintz-fold-cranes, make blintz-crane-creases on each square.
There are 13 models which are included blintz-fold-cranes.
