I think I took it when I was researching my first C&G wall hanging which attempted to show water breaking over a beach. When I'm feeling courageous I may post a photo - it doesn't look anything like this.
I like the repetition of the groyne [had to check the spelling of that!] posts and the reflections in the water, which are very stitch like. Lots of texture too.
While you are about it, it is worth visiting Joanne and Lynne's other blog which is wonderfully eclectic. I have Joanne's book on paper making which is very good and has lots of ideas for making books.
You could also contribute a paper boat to a worthwhile cause...
