I was contacted or contacted a couple of women on this board that live in my area. We met, then all 3 of us met together. Then we invited more to attend. We decided early on 1) how often to meet, 2) whether we bring food (duh, of course we do!), 3) what we want to do, and 4) what the name of our group would be.
So far we've taught more than quilting!!! All of us have quilted for some time, so we have taught how to make Christmas ornies out of fabric and how to make the folded star potholder. We always bring show and tell stuff. We're into our 3rd or 4th meeting. It's been a blast....meeting more people of like interests and getting out of the house. We've shared patterns, ideas, and encouragement.
I say, go for it -- maybe put an ad in Craigslist or the newspaper or nickle ads....and open up your home to others. Oh, ours has gotten so big we've found a neutral place to have the meetings!!!!
