Okay I just posted this huge thing on bamboo, I still think it is important to see if your bamboo fiber product is tested, but I just went to the website of the lady, who seemed to be telling the person with the bamboo sheets that cotton is safer, has a list on her site for organic retailers and there were quite a few for bamboo. So maybe she changed her mind about bamboo or something. I don't know I am still waiting to hear from bernat; although just just because product says organic cotton, linen, or whatever that doesn't mean that it had an organic conversion process that just means it was organically grown. So until next post.
