we did a fun activity last winter--one member, using a video camera, went to 3-4 members houses and filmed their quilting spaces, showing how they stored their fabrics, design walls, etc. It was really fun--two of our members really had the stash!
We also do a block of the month, where members bring one for charity and one for a member raffle (each block you make equals one raffle chance). Our charity quilts go to the county cancer foundation for clients and to anyone in the county dealing with fire, flood, etc.
We do a survey to find out what people are interested in learning and what they may be interested in "teaching" (give an option of "with others"--sometime people have wonderful skills but are shy about leading others). Also, if you have a LQS, check with the owner to see if he/she would be interested in giving a program on fabric--I found it interesting to know when fabric for holidays, seasons, etc gets ordered, how to deal with fabric bleeding, etc. and new products coming out.
