The 8 inch Log Cabin Trim Tool 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 tool over the center square and trim. Since each round is squared up before the next set of logs are added, the results are spectacular. The cutting requirements for the strip widths and center square are printed right on the tool! Combine these blocks with eight inch curvy log cabin blocks created with the Creative Grids Curvy Log Cabin Trim Tool (CGRJAW5) for unlimited design potential.
