I've just joined a guild for the first time and some of the things that are important so far are that everyone is friendly (check), they offer numerous classes throughout the year (check) they offer lots of opportunity to get involved (Still trying to see where I fit in there) they have a vigorous outreach programme within the community for charity quilts and other items that everyone takes part in (check) and they do a Show and Tell at every meeting (Haven't got up the nerve yet, but I will.)
So far it's been a good experience and I've enjoyed the speakers and local quilt shops that they have had come in. I haven't noticed any "cliques", but who knows?
I plan to offer my help with the upcoming quilt show and investigate another committee that may need help. I think that's how you really come to know whether a guild or group is for you...by becoming involved.
