There's a classifieds section on the board. However, quilters seldom buy quilts (except for vintage quilts) so ebay, craigslist, or etsy might be better. If there's a quilt show near you, you can often get a better price by showing it there, but the people who put on the show usually take around 30% of the sales price. It sounds high, but they provide a large pool of potential customers and you can increase the asking price.
