When I hand quilted a log cabin I just did a straigt line down the center of each log strip. I started ¼" down from the seam and ended ¼" from the next one crossing under the layers to get to the next strip all the way around. (I tried just quilting straight through all the seams, but it didn't look good and I hate to do the stab stitch) It was straightforward, but it looked nice and you could at least see the stitches.
