I belong to a guild with about 135 members - even joined the executive (newsletter editor & webmaster).
The executive meets once a month, the main meeting is also once a month, a couple of weeks later.
The main meeting always has a program and show & share - speakers have been wonderful, from Cathy Miller (the singing quilter) to Superior Threads speaker to just 'mixer' activities.
There are subgroups that put together comfort quilts, etc. I haven't been able to join those as they take place during the day.
Our fees are $35 for the year, which I consider to be a very reasonable cost for the chance to learn all kinds of things, to share the guild library and all the fun stuff we do.
There are all kinds in our guild - those with perfect, exquisite work; those with beginner skills who are also cherished; organizers and followers; doers and workers and yes, those who just plain will never be pleased with anything.
I'm having fun with this group!
