This is a origami modular pinwheel you can change it to a ring or a pinwheel.

Step 1: Supplies

Supplies: you need is 8 square pecies of paper,it can be any size as long as it's in the shape of a square.
(they can be any color you want them to be and you can also use cardstock).

Step 2: Step #1

Use one square piece of paper and fold it in half and then fold it in half again.

Step 3: Step #2

Unfold everything back to the original piece of paper, and then fold two corners into the middle crease then fold in half.

Step 4: Step #3

Turn the piece of paper to the left then, fold the bottom right corner into the crease.

Step 5: Step #4

Unfold the paper to where it only had two corners down. On the bottom of the piece of paper fold the two inner triangles by pinching it inside, then fold right and left side together.

Then repeat the steps from step #1 to make 7 more pieces like this to connect them together.

Step 6: Step #5: Connecting the Pieces

Connect the pieces of paper by inserting a closed side into a open side of a diamond, then fold the flaps inside the other diamond.

Then keep repeating this until you have a shape like a octagon or a ring like circle.

Step 7: Step #6

Halfway connecting the diamonds it should look like this picture.

Step 8: Step #7 Finishing Your Pinwheel!

Once you have finished connecting all the diamonds together, you should end up with something like this picture. To make the spikes come out just push the opposite sections together.

Step 9: Your Done!

To make sure its right it should look like this, and then your finished!! now you have a transforming modular pinwheel
(you can also return it to it's original shape (a ring) by pulling the sides)
