Cool, thanks for all the links!!
Someone here posted awhile back about bamboo batting, that it goes through a process that is not at all
environmentally friendly. That soy/cotton batting sounds really interesting!
I'm surprised there aren't more corn-based battings on offer...seems like the US has such a corn surplus. Can't they make polyester out of corn now? (Maybe I'm mixing things up and that's not possible...)
And of course for batting there's always the old-school (and very "green") method of simply encasing an old worn out quilt or blanket in a new top and back.
