Peckish -- I live in organic central of the US -- the term doesn't bother me at all, but I can see where you'd find the over-application to be annoying-- specially when everything from sheets to shampoo is labeled "organic".
However, in the context of an art style (and I'd class quilting as an art), it's a well established, long-used term; way back in art history classes in the early 80s I had elderly profs assigning readings about the "organic elements in Romantic period art and architecture."
