Where can I sell my cross stitch?

That's so cool. My mom is very interested in cross stitch and she has made large size of cross stitch like pictures. I ever asked my mom whether she liked to sell them as it could be quite expensive. But my mom was not willing because it spent her long time doing it. And it is not about money. She did it for fun and hobby. I think you can try to sell it online, such as Ebay. It is the most common way to sell online.
