I see a lot of posts where quilters think the quilt is ugly and a whole lot of people say " Please send it to me - I think it's beautiful!" My dad used to say " there's no accounting for taste!" So if you feel so inclined, finish it, but I wouldn't spend a lot of time and emotion worrying about the waste. I always equate it to dinner and a movie. Not a cheap proposition, and it's over in a night. But we fuss and fuss about that same money if it was in fabric, and often let it keep us from moving on.
