Finish it as it is. You can still make another for the intended recipient. Use this one for a picnic quilt, or just to cover up with for a nap. If you really can't stand it at all, donate it. There are so many uses for a quilt that is not what you intended it to be. Remember that a quilt is meant to keep someone warm, the decorative (pretty) part is an added feature. Grandmothers made quilts from scraps of fabric left over from sewing clothing. Sometimes we just get to "arty" and forget the original purpose of a quilt. Consider it "tuition" for a learning experience. If you have kids or grandkids you won't have any problem with getting rid of it!
