The 10" Wonky Log Cabin Trim Tool from Jean Ann Wright puts a fun twist on a traditional block. This ruler is designed to work with 2-1/2" strips for both the logs and center squares making it precut-friendly. After adding each round of logs, place the appropriate centering square on the ruler over the center square of the block and trim. Since each round is trimmed before adding the next one, your final trim squares up the block making it ready to be used in your project. The Wonky Log Cabin Trim Tool features easy-to-read black and white markings, making it easy to line up your blocks. Your finished block, not including your seam allowance, will measure 10" square.

As with all Creative Grids rulers, the Wonky Log Cabin Trim Tool slides easily over the fabric until pressure is applied. Once pressure is applied, their exclusive gripper technology holds the material in place, helping to prevent slipping and miss-cuts. The ruler has easy-to-read markings, and you can download free illustrated step-by-step instructions here. Made in the USA.
