Since each round is trimmed with the Creative Grids Log Cabin Trim Tool for 6-inch finished blocks, they are all the same size and come out perfect every time! Bonus directions included – supersize this pattern to 24in x 56in by using the Creative Grids CGRJAW5. 17in x 41in. The Creative Grids CGRJAW6 is required. The CGR218 is recommended.
