ONe of my guilds has two small "Bees". The larger of the two meets at various members homes. My friends and I found it to structured for us. A small group of us, three or four, meet in the classroom of a local Bernina dealer the second and fourth wednesday of the month for a couple of hours and then go out to lunch. We usually just bring along any handwork we are working on be it quilt related or not. We encourage each other and swap ideas and tips and tricks.
Small guilds have smaller groups that are really committees that do things like make the guild raffle quilt or plan and carry out a fund raiser that benefits the guild as a whole.
