Well this isn't good news! That stuff is expensive! I have 20 year old everyday quilts made from JoAnn's fabric that I wash at least bi-weekly in regular detergent and they're not even showing wear, much less deterioration. Reminds me of the crazy quilts of old where the silk has disintegrated because of the metallic salts used in the manufacturing of the silk. I, too, will be watching this topic.
