Sorry, but from a business point of view, I don't see how you could cover your rent/utilites. You must talk to someone NOT connected to quilting to get a true financial picture. Thinking about this from a participant's point of view, I would be more prone to organizing such a gathering at a full-service quilt shop that would be willing to rent out a room - then we could take a break and SHOP! And, if the meeting was charity related, I'm not sure you couldn't get a large quilt shop to donate use of the room for free. This would benefit the quilt shop in numerous ways, including getting new people in to see what they have to offer, while taking a tax break as well. But get some professional advice on this. Good luck. Paula
