Sarah Goslee, together with a friend, is proposing a new study group about archaeological textiles in the Complex Weaver's group. That does sound interesting - I've read a few of the newsletters from the Medieval Textiles group, but being no proper weaver myself, I never joined or participated. The new group will have a much broader focus, and I will definitely keep an eye on its development.
It's all still in the planning stages, but you can read more about it
on her blog.
