For those of you that are looking for more information about fabric that is processed without harmful dyes and finishes, and which fibers are grown organically, you might want to read about the GOTS certification. It's basically the equivalent of the, "Organic," label for food, only GOTS is for fabric. This is the official site which is...umm...rather..."official"... and might be hard to get through.

However, if you're interested, there are lots of blogs and organic quilting sites out there that have more simple, boiled down, info about GOTS fabrics. Maybe if someone finds a good one, they can post it here. I'll keep my eyes peeled too.
