Cut the cardstock down to a 6-inch by 6-inch square. Use the extra strip of cardstock to make a cover for your pinwheel by tracing around a coin and cutting it out. Use a hole puncher to make a hole in the middle of the circle. Set aside.

Fold the square in half diagonally to form a triangle. Press flat. Open it back up and fold it in half again to form another triangle using the opposite corners. Press flat. Punch a hole right in the middle of the paper on the edge of the paper.

Open the square back up. You should have an X running right through the middle of the square, from corner to corner, and a hole in the middle of the square.

Use scissors to cut along the lines of the X, starting at the corners of the square. Stop about 1 inch shy of the hole in the middle of the paper.

Use the hole puncher to make a hole on the left side of each line that you just cut. Be sure to leave enough space between the hole and the edge of the paper so that the paper won’t rip through easily. You should have 5 holes total; one in the middle of the square, and 1 hole along each edge of the square to the left of the diagonal lines you just cut.

Flatten one end of the paper straw and punch a hole through it.

Once all the holes are aligned, add the circle cover you cut out in step 1.

While holding all of the pieces in place, remove the paintbrush and place the brad fastener through the opening. Open the back prongs and press flat to hold everything in place!

Your paper pinwheel is complete! Take them out and enjoy watching them spin! You can also use them for a fun springtime decoration by setting them in a flower vase.
