Square piece of paper ( can do with construction but easier with origami or printer paper)
Patience (many of the steps shown are to guide future folds and repetitious)
Step 1: Start With a Square
Step 2: Making a Triangle
Step 3: Making Triangle Into Square
Hold the paper so you are looking at the open bottom side of the triangle. Open the bottom of the triangle and push down, forming a diamond.
Step 4: Starting the Base
Now lift one of the flaps of the diamond and push down to form a kite shape. Repeat for all flaps.
Step 5: Forming the Center of the Flower Part 1
Now take the bottom corner and fold into the center. Repeat on the other side. Repeat on the other flaps.
Step 6: Forming the Center of the Flower Part 2
Open out the last two folds into the center on each flap. Lift the center forming a small triangle and push that down. Repeat for each flap.
Step 7: Change of Flap
now take one flap and flip it over, should only see a smooth surface flap.
Step 8: Rotate Base
Rotate the base so that the point of the hidden triangle is facing away from you.
Step 9: Forming the Outside of the Flower
Take the bottom corner and fold into the center, repeat other side. Repeat on other smooth diamond flaps.
Step 10: Forming the Petals
now take the top portion of the flower and fold down flap. Repeat for each flap. Then curl petal over finger.
Step 11: Origami Flower Complete
All done. The petals keep shape better with origami or printer paper.
