First I cut a 2" square and then I folded it in half and creased it in half so I could find the center easily. Notice the red ink mark. I purposely used some paper that had a flaw on it because I knew I could cover it up and I just couldn't let it go to waste.
Open the square back up and then I made marks 1/2" from the center on all 4 creases.
Cut along the creased line from the corner in to the pencil mark.
Fold one of the cut corners in to the center and adhere it with adhesive. I used a glue dot. Repeat on remaining 3 cuts. until pinwheel is formed.
And here is the pinwheel. Can you see the red ink mark?
