Until fairly recently, I rarely used borders on my quilts, but I have been adding one border recently. I now want to expand to adding two and up to three borders of varying sizes (e.g., 3"/2"/3"). I am a bit (well, a lot) confused about what the Total width (one border, two borders combined, or three borders) of the borders should be. I read that a border should be no larger than the largest block in one's quilt, and preferably smaller. Is this correct? (To be specific, I have a quilt top that I want to add an inner border of 3", a middle border of 2", and the outer border of 3", (finished) but this comes to 8 inches, and the largest block is only 6 inches finished.

I hope this question isn't too confusing; I'm confused enough myself!

Thanks for any advice you may offer!
