There are 2 methods for processing bamboo.. one is "natural" and doesn't use harmful chemicals.. but takes MUCH longer to process and much more work. the second uses enough chemicals that it totally negates the "green" benefits.. so until they find a third option I'll stick with cotton. That is why they quit making so much linen.. retting it takes a LONG time and you have to stomp it and tend it daily to process it properly.
