Flow + Builder
Designing your own WordPress themes has never been this easy! Use Flow to design the theme appearance (header, sidebar, footer, and templates), and then build the page content with the Themify Builder plugin. Simple, but powerful and flexible. Combining the Builder with Flow gives you full control of complete site!
In case you are not aware, this theme is created with Flow. Click around on this demo to see how Builder is used in Posts, Pages, and even WooCommerce Products.
