Today it is a 4-leafed Buttonhole flower.Model is created by Paul Jackson.
This buttonhole flower looks best when the paper is the same color on both sides. If you use origami paper that is white on one side and colored on the other, be sure to fold it so that the color side is inside the folds - the color will be visible only at the final step of the project.
I came across this model while seraching for the base units of a kusuduma .Initial try with the flower was diaster as i couldnot make out the folds direction properly,even though it is such a easy fold I kept on messing with it.
But trust me its really easy fold...
If you are using origami paper that is white on one side, start with the white side facing up.
Fold the paper along the diagonals
Collapse the paper into a waterbomb base. To do this, bring the top of the paper down towards the bottom while pushing the sides inwards.
Step 4:-You would get a triangle with flaps
Rotate Triangle upside down
Fold two layers back to the left side as shown below.
There is central axis hold that and open the flower flaps as shown
Step 11:- Use your fingers and open the flap layers so they look like petals.This is important part it gives final shape to the flower.
