I personaly prefer SID pm the Log Cabins. However, think about where you want the focal point to be. Is it the logs and the arrangement of light and dark or a quilting pattern. You could select a wide border design to quilt down the light and dark sections. However, I would use a non constrasting thread to just add texture and not new design. This would depend on your skill of doing free motion quilting. However, there are some border designs that could be stitched with the walking foot.
My first consideration would be, as stated, a quilting that would not detract from the log cabine design.
