I remember paper napkins on sister's heads in their homes, when I was a child.
I also remember a WT article where they said not to use things that aren't true head coverings. It should be a hat or a scarf. Evidently the napkin, paper towel route is not acceptable.
OTWO....Thanks for correcting me. I have to say in all my years I, too, never heard any JW call the org. "Mother"....ever!
I've heard that as long as I can remember and my parents became JW's when I was 4. "Mother" was the term for the organization.............or "our mother" "we have a letter from mother", etc.
