http://www.quiltropolis.com/ This website is a portal for all things related to quilting. They offer the ability to set up your own shop. I have a friend who sells fabrics online this way. You could browse the shops there to see if any do consignments. They have classifieds, too.
Etsy is a great website that you can sell your handmade goods on.Craftmall.com is another popular website that deals in selling handmade crafts such as yours. I used to sell my handmade jewelry there on occasion for extra cash. http://www.craftmall.com/index.htmlAnd of course there is http://www.strictlyhandmade.com/homeI cannot speak for stricklyhandmade.com but the other 2 are great sites that I think you would have success with. Keep in mind most websites like this do not charge an upfront fee to sell your goods but instead they charge you a small percentage of the what the item sold for. Give them a try I think you might like them. Good luck!
