This instructable shows how to make an origami rose headband

This includes the following

Making the rose petals
Making the sepals
Decorating and assembling the rose on the headband

Step 1: Tools and Materials

Full size red origami paper (here we use 21 cm x 21 cm )
1/4 size green origami paper (11.5 cm x 11.5 cm)
Headband
Ribbon (to be glued on the headband)
Hot glue gun
School glue
Super glue
Scissors
Tweezers (optional)

Step 2: Find the Reference Point

Fold the 21 cm x 21 cm paper in half.

Then fold it in half again so that you get 4 square shapes. On one of the squares (left one in the photo), fold along the two diagonal lines. The cross point is the reference point to be used in the next step.

Step 3: Cut the Pentagon Shape

Use the reference point we found on step 1 ( point B) , fold the paper so that point A will be on top of point B

Notice that the middle (point C) is not the same as point D

Cut it along the line so that you can get a perfect pentagon shape out of the origami paper.

Step 4: Start Folding the Petals

At the end of previous step, you get a perfect pentagon shaped origami paper.

This pentagon will be the body of the rose.

Grab the pentagon origami paper from the middle, making it stand up like a star.

Notice the yellow line? Fold it from the yellow line. The width of the line actually depends on how you want the rose to feel. In this demonstration, I folded it about 1cm wide.

After you finish folding all five sides, you will get something similar to the 4th photo.

We can now flatten it so that you get a pentagon with folded sides again, as seen in the last picture.

Step 5: First Layer of Petals

Flip the pentagon over.

Now pinch the paper along the lines and swirl-fold the paper.

After you finish all five sides, flip it over again, and you'll have a very basic rose-like flower.

The last photo is from the side.

Step 6: Making the Second Layer of Petals

Pull each side outward and then fold along the line.

Repeat for all five sides.

Step 7: Flip and Fold Each Petal

For each petal, flip and fold it as it demonstrates in the photo.

Step 8: Unfold and Redo

Unfold the flower and re-fold it again along the lines.

At the end of this step, you will have a cylinder shaped rose.

Here is a top view and a side view.

Step 9: Fold Down the Petals

To finish each petal, curl the outer petals tip down.

After finishing all the petals, you'll have a rose.

Here is top view, side view and bottom view.

Step 10: Adjust Each Petal

Adjust each petal to make it look more real.

Here is the top view and bottom view.

Step 11: Making the Calyx

Following step 2 to cut the 1/4 size origami paper to pentagon shape, grab it from the middle and make it into a 5-point star, as seen in the picture above.
