I just loved making these pinwheels. Here's another one for you. I made about 20 of these with all different phrases using the Teeny Tiny Wishes set. This was one of the cards I used for our team meeting swap. You can refer to my video on how to create this cloud technique here.
To make the pinwheel part, just cut a square. For the one on my card it was just a 2 1/2 x 2 1/2 square. You can use any size square for this. It's just if it's smaller it will be harder to work with. Find your center as shown in diagram. Follow the arrows and cut up till you reach about a 1/4" from your center (depending on the size of your pinwheel). There's not an exact science.
Adhere adhesive to the center where the black dot is. The red dots on the diagram indicate the corner that you want to bring up to the center and stick to the adhesive. Apply more adhesive and bring up the next corner denoted by the red dot, and keep doing this four times in total to create pinwheel. I then secured it with a brad.
Here's my other pinwheel I mad a few weeks back.
I hope these directions help.
