The third in the Tucker Trimmer series of rulers, this version of our Tucker Trimmer is used for any block or unit that is larger than a 6" finished block size. It has all of the sizes of the Tucker Trimmer I plus thirteen additional size options up to and including trimming blocks to 13" (that will finish to 12 ½" when sewn). Deb Tucker loves to use this tool to trim down her Lemoyne Star blocks made with her Rapid Fire Lemoyne Star tool and any type of block that needs to be trimmed and squared to a specific size. A terrific tool with all the same benefits as the original Tucker Trimmer.
