that patterns in the examples are from the html version, not the wordpress theme. I can send you the images to use. You have to upload the patterns in the page Media > Add New and copy the link.
Then, you go to Appeareance > Theme Options > Custom Scripts, and type the next code in the field ‘Custom CSS’:
background: #fff url(link_pattern) repeat;
In this example, I have used the section sportlight1, but you have to type the sections you want.
