If you absolutely can not stand it then get rid of it. No matter what you do to it you still won't like it. Donate it to a quilt guild, a church that has a sewing group, put it on Freecycle, Let it Go, or even Craigslist for free or just drop it off at your local thrift shop. Someone will love it, beauty is in the eye of the beholder, do not keep it if it doesn't bring you joy and you hate it. It's not worth the space it takes up in your sewing studio.
