Did you have any luck? Now I'm looking for the same - do you have any to pass on to me?
I'm also interested in an affiliate program with them.
Thanks & best,
What is your opinion on Modal?
"Modal is fast becoming a popular fiber for high quality clothing and is a bio-based fibre. It is 50% more water resistant then cotton, doesn't pill like cotton, and is resistant to shrinking and fading."
Not sure if it is quite as friendly as organic cotton but it certainly looks like a step in the right direction.
