At our retreats we had one or two that
were annoying, talking constantly. We
assigned tables and put them together
It made one fuss that she couldn't get
anything done but she never realized
she was guilty of the same behavior.
We were blunt with her. It didn't help
She is no longer in the guild. The other
one learned from the experience and
has become less chatty during sewing
times. You should not let one person
spoil it for others. Try kind first then
be firm with I don't have time to help
you now. Sometimes it will work and
sometimes you will lose a member
