The 10" Wonky Log Cabin Trim Tool puts a fun twist on a traditional block.  The tool is designed to work with 2 1/2" strips making it precut friendly.  Each round is trimmed before the next round is added when the final round is trimmed your block is ready to use in your project.  All Creative Grid products have the exclusive grip system that allows the ruler to slide over the fabric until pressure is applied then the grip system keeps the fabric from slipping.
