The Tucker Trimmer tool was designed to help quilter’s quickly and easily trim down units that are made with triangles: half square triangle squares, quarter square triangle squares (hourglass units), and combinations of half square and quarter square triangle squares (combination units). It has multiple diagonals which allow you to align ruler guide lines with unit seam lines to quickly locate the exact center of pieced units. This makes trim down easy,precise, and perfect every time. No more figuring, or guessing, or struggling to find a center point, and you can see it demonstrated on our free online video demo. I use it for much more than just trimming however and consider it my “must have” tool every time I head to my cutting table. 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). I love to use this tool to trim down my Lemoyne Star blocks made with my 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.
