Hi, I would like to make some soft fluffy pillows for the back of the sofa. I have the covers. I don't want to use polyester or bamboo stuffing. Wool would be fine, or cotton. I was reading that cotton batting has pesticide residues if it is not organic.(anyone know if this is true?) Can I buy wool or cotton batting and pull it apart to make stuffing? I can't seem to fine any affordable wool or organic cotton stuffing that is "in stock" One site I read said cut up wool sweaters, would this be fluffy? I know I just asked a bunch of questions. Help with any of them would be great. Other ideas for making my own stuffing or if you know where I can just buy stuffing would be so helpful. I need to make at least six good sized throw pillows to cover the back of the couch. Thanks.
