Do a browse on quilt retreats, then when you find some places you could reach out to them. They can probably put you in touch with some groups that have rented space to see if they might have space and need someone to join them. I know in our area while the quilds and shops do retreats, so do small groups and groups of friends that sew together. Often when we are wanting to go someplace where we can't meet the minumum we will ask everyone to reach out to find someone.
