A sheet of square origami paper (6" x 6" / 15 cm x 15 cm)

A flat surface

A pencil

Steps

Make
diagonal creases and unfold
With the paper colored side up, make a diagonal crease by folding one
corner to the opposite corner. Unfold. Repeat with the two other corners.
You should now have two diagonal creases on the colored side of the
paper

Fold
corners to the center and unfold
Turn the paper over to the white side. Fold all four corners to the
center and unfold

Fold
edges to opposite edges
Fold one edge of the paper to the opposite edge. Unfold. Repeat with
the other two edges. Do not unfold.

Bring
four corners together
Position the paper so that the folded edge is along the bottom. There
should be creases on the paper that form a “V.” Hold the
paper with each hand on either side of the “V” and slowly
bring your hands together, allowing the four corners to meet at the
top

Place
model on table
Place the model flat onto the table, making sure there are two flaps
on the right and two flaps on the left and the closed point is at the
top

Flatten
down a flap
Take one of the flaps and stand it up so that it is perpendicular to
the table. Insert a finger between the layers of the flap to spread
them open. Flatten down the flap, aligning the center vertical crease
with the white layers underneath. There should now be two small white
triangles at the bottom of the model.

Repeat
on the other side
Turn over and repeat on the other side

Rearrange
and flatten remaining flaps
Rearrange the flaps so that you can perform the same maneuver (squash)
on the remaining two flaps. When you are finished, make sure that there
are now four flaps on each side and that two white triangles are visible

Fold
the white triangles to the center
Working with one layer only, fold in the sloping side of the right white
triangle to align on the center vertical line. Repeat on the left side.
Unfold both sides

Lift
the bottom edge and flatten
You now have a large colored triangle above two white ones with creases
running through them. Lift the bottom edge of the colored one up and
back as far as it will go, drawing the sides together. The sides of
the white ones should meet along the center vertical, forming a kite-shaped
flap. Flatten this down so you don’t have any white showing.

Flip
the model and repeat
Turn over and repeat Steps 9 and 10 on the other side.

Flip
the model two more times and repeat
Rearrange the flaps and do Steps 9 and 10 on the remaining two sides.

Fold
sloping edge to center line and repeat
Rearrange the flaps evenly so that there is a plain surface (without
any flaps) on the front and back. Starting at the closed end of the
model and working with one layer only, fold the sloping edge to lie
on the center vertical. Repeat on the right side.

Flip
model and repeat
Turn the model over and repeat Step 12 on the back.

Rearrange
and flip
Rearrange the flaps to reveal the two remaining plain sides and repeat
Step 12 front and back.

Fold
down four flaps
Rotate the model so that the closed end is at the bottom. Taking each
in turn, fold down the four flaps at the top of the model to form petal

Arrange
petals
Arrange the petals to your liking, then stop. . . and smell, or at least
admire, your flower

You can give the petals a nice curl by wrapping
them around a pencil.
