Blondie, you may be right. It seemed to happen alot until there was a part on the meeting about what was and was not appropriate head covering.
This was in the late 60's , I remember seeing my mom wearing a scarf on a normal putting to protect her hair. She got it "done" once a week. So it was surprising that she did not have one with her.
These sisters did not want to conduct. I think they figured if they didnt have a covering so someone else would have to conduct.
