I looked at the fabrics in the link. I'm not impressed. So, I won't be spending my hard-earned $$ buying those fabrics.
And as others have said, "organic" is a term that can be completely abused and misused and misinterpreted in so many ways. Considering that 90+% of any fabric greige goods start off in China, I think we all have to take any claims of "organic" with a grain of salt. We all know that China is one of the worst places in the world for using toxic chemicals to produce everything - they don't care about their people, nor the consumers.
Just my opinion...
