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 1 plus thirteen additional size options up to and including trimming blocks to 13" (that will finish to 12 ½" when sewn). Use this tool to trim down 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.
