The 8" inch Log Cabin Trim Tool Template features exclusive markings to create perfect finished Log Cabin; Half Log Cabin; or Courthouse Steps blocks. After adding each round of 'logs', place the appropriate centering square on the ruler over the 2 inch finished center square and trim. Since each round is squared up before the next set of logs are added, the results are spectacular. The suggested strip widths are printed right on the template! Size - 8-1/2in x 8-1/2in
