I think group quilting is about learning and friendship. There will always be cliques.
The fellowship hall has very few outlets and most are along one wall. So the room is set up with long rows of tables connected together. The tables are 2 back to back. The teacher can stand to the side.
The library is smaller and our group is much smaller so we usually have a U or lg square shape away from the wall. The cords go across the floor.
