I would look at ebay or cragslist to actually sell them. A lot of time on quilting boards people like to quilt their own quilts. I would however get as much exposure for your quilt tops as possible. any place that you can sell is where I would sell them. Even if it means listing in a couple of places. With the exception of ebay. I would only do one or two on there depending on how many you plan on making to sell.
