Check with local guilds. Sometimes they have a venue where you can sell a quilt and they get part of the proceeds. My guild, for example, has an auction at our annual quilt show. The quilter can either donate the quilt outright or receive up to 50% of the sales price. Other guilds will allow you to show quilts in their quilt shows with a "for sale" tag. Their commission is usually 20-30%. Your quilt can be displayed at the Sisters Outdoor Quilt Show with a "for sale" tag, and again they take a percentage. I know these costs seem high - up to 50% - but the quilts do get sold, and sometimes at higher prices than you might get from an online listing. Ptquilts is right that people are more likely to buy if they see the quilt in person.
