I don't cut logs. I sew together long strips to start. Then I cut the strips down to the width for the 1st 2 pieces. Then I add the next color......a long strip with the cut pieces sewn one after another onto that strip. Then I trim them to size and cut the next strip to sew those to. I go on and on..... so much easier.... just keep your colors straight (I usually make one block for a sample). I made a log cabin quilt, queen size, in a week using this method. I can't imagine cutting tons of logs.... that would drive me crazy.
