Every other year we have one meeting be a quilt college meeting. We have 6 members do a little demonstration 3 times during the night and the guild members rotate to the presentations they are interested in.
We've had: demos on hand quilting, machine quilting, some type of piecing technique, demonstrating how to make yo yo's or hexie quilts (hand piecing) all kinds of things. It saves us from having to have a speaker that night.
Each year we have the members bring their machines, cutters and irons and we sew for charity.
Another idea is we have done row or round robins. Those would be worked over several months and they are fun to unveil at the end of the event. Usually the beginning or center block would be supplied by the eventual owner of the top. It is passed to the next participant who adds a round, then the next month it is given to someone else to add a round.
Let me know if you have any particular questions.
