You may know exactly where to find your SARAH Sisters. You may even already have a group waiting in the wings to join you in circle. Regardless, it's always nice to expand your circle and also insure you have a good diversity of religion, culture, ethnicity and age.
Check your community for an interfaith council or councils. Contact them and ask if the women might be interested in dialoguing with women.
Check your local university or college for comparative religion, women studies, (or similar departments).
Contact the local churches, synagogues, mosques, gurdwara, temples, etc. and ask the clergy or women's sisterhood to recommend someone interested in interfaith dialogue.
Either walk in or give them a call.
It's ideal to invite each woman to bring a friend.
