Hi, I have a flannel quilt ready to quilt but need advice. The top is multiple colors of blue, rust, and brown. The backing is a small brown print. One of the borders is a tone on tone blue and I would like to quilt it with a blue thread but don't want to use blue in the bobbin. Would it look okay on the top if I used brown thread in the bobbin? How do most of you quilt? Do you always use the same color on the top and in the bobbin?

Thanks in advance for your help!
