I just love pinwheels on a layout...they just make me smile! I tried to make the directions as simple as I could because they first tutorial I found, was really tough to follow. So here it goes.
Step 1: Gather supplies...double-sided patterned paper, paper trimmer, pencil, scissors, and a brad.
Step 2: Cut your patterned paper in a perfect square. For this tutorial, I cut the square to 5 inches.

Step 3: Draw a big "X" across the square. With the cross in the center of the paper and the ends of the "X" to the corners.

Step 4: From each corner of your square, cut towards the center of the square. DO NOT cut to the center of the square. Stop cutting at about 1/2 an inch before you get to the center.

Step 5: Now...if you look at the square, you should have 4 triangles. Punch a whole in the left hand corner of each triangle and the center.
Step 6: Fold over each of the punched corners to the center securing with a brad.


There ya have it!
Here is how I used 2 pinwheels on my layout.


I can't wait to see some of your layouts using pinwheels!
