Actually if you overlay template with the colored picture in Photoshop, the template on one layer and the texture on another layer, you can see that they do line up. The black splotches at the bottom lay in the same position as the spokes and the leaves pattern does have a curve in it which matches the curve of the fan. To make your own pattern just follow the example of the texture pattern in the sample. In your paint program put the template on one layer, put another white layer on top of it, and then make it transparent, and on the third layer put your picture. Then before you save your picture, make the middle layer opaque again. This will hid any of the template from peeking through.
