I am in love with log cabins now; very afraid when I did first one. Squaring after each round not necessary in my book. I square up each block when finished. I also make last 2 logs a little wider to give me leway. I do not precut length of logs; they get moved to often in my small sewing space. I cut log after sewn. Much less confusion. As long as each finished block is squared up no matter what the design is , usually very little squaring up is needed on finished quilt. Hope this helps,
