Hi there, First, I had to look and look for your "mistake", and when I did find it, I remember someone saying that only God is perfect, and any mistakes that a quilt has, it is a kiss from an angel blessing your quilt. Now, binding color. Depends on what you like....I would stay with the blue.. it extends the border a tiny bit.
