Wow, you’re in a very active group!
I'm in three quilting groups. For one of them, we meet at a Senior Center and we make items to donate to their bazaar. In another one, we're making pillowcases for teenagers with cancer and in the third group, we're making the heart shaped pillows with matching bags to be given to ladies who have just had mastectomies.
Each of the three groups puts on a yearly retreat, which are always wonderful.
Two of the groups meet monthly and there is a business meeting before the event. The event could be a trunk show, a guest speaker, "4 corners", which is where someone is in each corner of the room to show someone something new. There are Saturday open-sew days for $5 each, which covers the rental of the place we have it at.
The other group meets twice a month. One is a business meeting and the other is a learning session. This group sometimes has full day Saturday classes, usually taught by a member. These are usually for something that need more time than our two hour time slot for a regular meeting.
