I actually thought of that!! But I couldn't visualize it. I hung it up and tried the suggested white, then red border - that was good. The dark blue, then red border was even better. I may stitch up a couple of feet of sawtooth and see what happens. I also thought of strippy triangles sawtoothed with red triangles - again, I just can't 'see' it in my head. So many liked it as is and I have in mind something I want to try (candlewicked quilt), so it may have to stay this way "just because".
Thanks to all!! BJ
