I wonder if that’s the way to go.
I am in the process of designing my theme, built off a framework, but the theme is NOT a child theme.
I think there is some confusion here.
If you build off a framework, then you should end up with a parent theme. Period.
If you need to mention a ‘template’ in your CSS, then that CSS belongs to a child theme. And if that is the case, then you are building off from a PARENT theme, and not a framework.
Am I even making sense here?
In terms of business models, I think building child themes for famous ‘parent themes’ like t that of genesis etc, is more like a ‘franchise’ model.
And franchise models usually do not work. Unless of course the main company gives you way more support than you’d typically expect (like McDonalds with their franchise universities and what not!).
I remember asking these questions of going for child themes (the easier route) vs making my own parent theme. I decided for a parent theme, purely because I did not find that big an edge designing and developing for another brand.
