Here's a question ... even if you DID find some organic ribbon, how in the world will you find organic clips/snaps/etc to put it on?!?!? I'm pretty sure those aren't really 'green,' ya know?
Would that throw the whole thing off? Or could you be a bit sneaky and put "Made with organic ribbon & thread" and just sorta ignore saying anything about the clip? That's the sort of thing I would notice if I were shopping organic.
I really, really think something like this would be neat, but there are just so many questions running around in my head about it that I probably won't be able to worry about it until there's more research on the subject.
