As an addition to my article on how to use the Thesis Custom Loop API, here is a Custom Loop starter template you can use for your own loops. Every loop you can customize in Thesis 1.8 is stubbed in, and comments before each method provide helpful reference information. All you need to do is replace the one-line stub methods with your own custom loop code. You can delete any loop method you’re not customizing, or leave them in place for the future; they simply apply the appropriate default Thesis loop.
