My advice would be to find a place where it is the same place every month, as well as the same day and time. We always meet on Second Mondays from 5:30 to 8:30 pm.
What happens at our gatherings? It is a potluck, so everyone brings a dish. We also provide wine, tea and water. Upon arriving, folks mingle and partake in the potluck. Then, we sit in a circle and my husband moderates. Everyone introduce themselves, saying what they do and what is new and good in their life plus any announcements to share. He demonstrates by going first. He recommends that there be no cross talk. Otherwise, we might be there 'til two in the morning! If you have a question for someone, you can always go up to them after this part.
A new component of our gatherings is our speaker series. This was Leslee Ortega's brilliant idea. She spearheads organizing our speakers each month which has been highly successful. We've had writers, a musician, artists, a puppet maker, a creativity coach and this month an artisan baker will share her story.
