OCWS Natural is a child theme, developed to work with the Natural Lite theme, which has been designed by Organic Themes.
The Natural Lite theme was chosen by a client of mine, but they wanted a number of variations on the theme. However, the premium Natural theme was very expensive, and the amendments that I needed were not great, so I chose to produce my own amendments for the client, and keep them in this theme.
The code is held at Github. If you want to try helping, you would be very welcome, but please fork the code, so that we can all be clear what is going on.
