Beautiful quilt and a lot of work! Where are you going to advertise it? Do you have a LQS that might hang it up with the price on it? If it was appraised at 1500 to 1800 I would try to go with that first, then if it doesn't sell in a reasonable amount of time, drop the price if you really need the moving money. I've seen quilts priced higher than that and not look near as intricate as yours.
