I have found you get more on Etsy, but may have to wait awhile to sell, whereas Ebay is quicker to sell but people are not willing to pay as much. Etsy is more for artists and craftspeople, and ebay is more a large garage sale. Both have their benefits.
Beautiful quilt- good luck selling it!
(If you don't/can't/won't sell it, Churches often have chartity auctions, or hospitals often accept blankets for sick children.)
