Not sure if I can describe this right but here I go. First border approx. 1 to 1-1/2" wide, dark color(darkest color in the quilt as long as it looks good when you audition it). Second border, I would make it out of a single row of the same blocks that are in the quilt(hope that makes sense). Third border, make it a larger size out of another color, probably a darker one, that looks good when you audition it. The second border of blocks will tie beautifully in with your quilt I think. Clear as mud right?! Whatever you do it will be gorgeous!
