I agree, add a nice contrasting sashing and it will spring back to life. As quilting mistakes go, this is relatively fixable: the fabrics work well together, they're just too similar in pattern type and value. And if you still don't like it after that (and it's not my style either, though I think it's perfectly respectable in its own way), then donate it to an old people's home or similar. If you're going to donate it, perhaps just tie it instead of paying to have it quilted. Assuming that tied quilts are accepted in those circumstances, of course.
