I like 4 or 5 best. However, I have to agree with someone else that suggested a different binding than the stripe.
Somehow, that takes your eye away from the great quilt and doesn't tie it together as well. Binding should always
tie in the body of the quilt and not stand alone, like I think the stripe does. You did a great job on this quilt and it will look great when it's finished.
