Use a six-inch square of paper (colored on one side.)
Fold in half diagonally.
Fold again in half diagonally.
Spred out from the inside and fold again to make a small square.
Do the same as step 4.
Fold left and right corners to the center line (fold on red valley lines), and then fold top corner on the blue valley line.
The figure should look like this.
Pull the bottom corner up and fold down again. Some folds will be inverted.
Turn over and do the same (Step 6, 7, 8).
Now you get Crane Base.
