I have done the same thing myself and it is a very frustrating feeling to have. However after I get it quilted all those unmatched points and seams are not hardly noticed. I think it adds character to our quilts. I am my worse critic.
When I have a top that the seams and points don't match and I make the pattern again I can do a better job. I tend to keep the one with the most mistakes for myself and give the better quilts to others. I think quilting is a learning experience and I love all my quilts that I have learned to create.
Your quilt is Beautiful! You did a wonderful job!!
