I posted this info on another of the Boom pages. You can order these bags as they are wonderful. The postage is still only $.44 to send.
there are also poly mailing bags that can be used to mail fabric without the need to wrap them in plastic. you can purchase them on ebay. i receive charm packs i order from some of the quilt shops this way. they are relatively inexpensive and they are difficult to rip open. i know, i have tried to open a couple of them on my way home from the post office after receiving a package.
