The largest problem you have is that your market is so limited. There aren't many people who hand quilt anymore. Getting your ad in front of those few who do is the challenge. Facebook marketplace, Craigslist and Offerup are a few of the places I would try. You might contact your local quilt guild for guidance (you will probably have to attend a meeting). Contacting your local quilt shop for advice is an option as well.
